DataMaps : Map-like Visualization for Non-spatial Data
▻http://talent.au.dk/phd/scienceandtechnology/opencalls/calls-on-specific-projects/august-2018/datamaps-map-like-visualization-for-non-spatial-data
Merci @fil d’avoir signalé cette proposition. Pas que j’envisage de faire un PhD mais le thème est vraiment intéressant et important, je le poste ici pour pouvoir y réfléchir (avec la communauté seenthis).
Research area and project description:
Are you ready to step onto uncharted territory and to map the unmappable? Maps are powerful tools for viewing, navigating, and communicating spatial information. By mapping geospace onto screen space, maps provide a spatial frame of reference using a commonly understood set of visual elements. This concept comes so natural and is so compelling that we even apply it to information that does not necessarily have a geospatial reference – for example, Site Maps for website structures or Mind Maps for thoughts and ideas.
This PhD project sets out to bring map-like space-filling visual representations to non-spatial multi-variate data in general, such as biomedical data or financial data. For data like these, different ways of turning them into a map are possible – leading to different meanings of a data item’s position, of the distance between two data items, and of the area spanned by multiple data items. It will be your task to research such meaningful “DataMaps” that bring added value to the visual analysis of multi-variate data.

« Mon travail cherche à mettre en perspective et matérialiser les effets du code et des données dans les pratiques et les représentations. Pour faire face à l’irruption massive de l’information, on assiste actuellement à un engouement pour les technologies graphiques qui visualisent des flux de données en tout genre et cherchent à donner un nouvel éclairage sur les affaires du monde.

Le graphique trompeur de la direction de la SNCF sur le taux de participation à la grève
▻http://www.lemonde.fr/les-decodeurs/article/2018/04/18/le-graphique-trompeur-de-la-direction-de-la-sncf-sur-le-taux-de-participatio
Et s’il suffisait de changer l’échelle d’un graphique pour minorer le taux de participation d’une grève ? Un communiqué de presse du siège de la SNCF paru le 18 avril et faisant le point sur le taux de participation à la grève de ce jour veut démontrer, graphique à l’appui, que ce dernier a largement baissé depuis la mobilisation du 13 avril.
Las, l’#échelle utilisée pour ce #graphique donne une perception déformée de la réalité : si ce dernier semble indiquer que la mobilisation a baissé aux deux tiers, ce n’est en réalité pas le cas. L’écart de 2,66 points entre les deux journées de grève ne justifie pas la représentation donnée dans le graphique. La valeur minimum de l’axe a vraisemblablement été modifiée pour minimiser l’ampleur de la grève.
[…]
Ce n’est par ailleurs pas la première fois que le service de communication joue avec la notion d’échelle pour minimiser le taux de participation des grévistes : un communiqué de presse diffusé le 4 avril utilisait les mêmes méthodes aux mêmes fins.
À la décharge de la SNCF, on peut remarquer que les options d’échelle retenues dans un cas comme dans l’autre sont les choix #par_défaut d’Excel (l’algorithme qui décide si l’axe doit comprendre l’origine est particulièrement niais (et documenté (ou du moins l’était parce que pour le moment je n’arrive pas à le retrouver…))
Ne pas nécessairement imputer à la malveillance ce qui résulte simplement de l’ignorance…
(ne pas modifier les options par défaut…)
« l’ignorance » du service communication ... est-ce un argument recevable ?
Recevable, certainement ; convainquant, c’est visiblement moins sûr ;-)
Dans un service communication, les connaissances en #sémiologie_graphique sont souvent limitées, voire nulles. Et les interventions « graphiques » se résument bien souvent au choix des polices et des couleurs (là aussi, hors sémiologie).
Plusieurs commentaires font part justement de ces subtilités sémiologiques, dont le fait que pour représenter la part d’un tout, il vaudrait mieux visualiser aussi le tout (en empilant, p. ex., une barre « vide » montant aux 100%).
Un autre (ce n’est pas moi…) reprend l’argument des options d’axe par défaut des graphiques d’Excel (tout indiquant que c’est bien le logiciel utilisé en l’espèce).
Même sans être convaincu, il est bon d’avoir ce doute à l’esprit…

The Globalization of Migration : Has the World Become More Migratory ?
Although it is commonly believed that the volume, diversity, geographical scope, and overall complexity of international migration have increased as part of globalization processes, this idea has remained largely untested. This article analyzes shifts in global migration patterns between 1960 and 2000 using indices that simultaneously capture changes in the spread, distance, and intensity of migration. While the results challenge the idea that there has been a global increase in volume, diversity, and geographical scope of migration, main migratory shifts have been directional. Migration has globalized from a destination country perspective but hardly from an origin country perspective, with migrants from an increasingly diverse array of non-European-origin countries concentrating in a shrinking pool of prime destination countries. The global migration map has thus become more skewed. Rather than refuting the globalization of migration hypothesis, this seems to reflect the asymmetric nature of globalization processes in general.

« La Graphique est un moyen de communiquer avec les autres. C’est son emploi le plus connu. Elle sert aussi à poser et à résoudre un problème. Cet usage dépasse maintenant le cercle des spécialistes et devient à la portée de tous grâce à la réduction des contingences techniques et à la simplification sémiologique. Mais la Graphique va plus loin encore en donnant une forme visible à la recherche et à ses méthodes. Pour prendre intimement conscience de tout ceci il faut réapprendre à “voir”.

Data visualisation mistakes — and how to avoid them
The FT’s chart expert outlines some basic errors and simple fixes

Pakistan’s education inequality was barely noticeable in the original chart; now its bias against girls becomes the standout story © EPA
There is a moment in Double Indemnity, the 1940s Hollywood noir classic, when you finally realise that anti-hero Walter Neff’s attempt to get away with murder will end badly. His colleague, Barton Keyes, suspects foul play in a seemingly straightforward insurance case.
What makes it clear that Neff is up against a master logician? Keyes has outsized charts on his office walls that project a bold message: beware the intellectual power of an executive with a firm grasp of the facts.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2Fd6e15e9a-d12a-11e7-b781
Walter Neff (Fred MacMurray) in Barton Keyes’ (Edward G Robinson) chart-filled office
Fast forward to 2017 and the intervening decades have not necessarily been kind to the use of charts in business. My colleague Andrew Hill wrote recently about a survey of business leaders’ preferred formats for insights: “None favoured infographics, which too often emphasise ‘graphic’ over ‘info’.”
Pejorative connotations of the word infographic often start from this perspective as corporate designers, desperate to dress up “dull” data, veer away from facts towards aesthetics. Reclaiming the value of charts requires a fundamental rethink.
In 2014, Unesco asked me to review graphics published in a series of reports on access to education in the Asia-Pacific region. I spent a pleasant week in Bangkok working with a knowledgable and talented team whose passion for their work was unquestionable. We spent most of our time discussing why the charts in their reports were uniformly awful.
For example, take Figure 7, the memorably titled “Gender Parity Index of the adjusted net intake rate in primary education, 2009” from the report on Universal Primary Education.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2F21aaa5b6-d12c-11e7-b781
UNESCO’s Figure 7 from Universal Primary Education: Gender Parity Index of the adjusted net intake rate, 2009
This chart breaks one of the first rules of data visualisation. It is not self-sufficient.
Assuming we know what the Gender Parity Index is, it is not clear what purpose the mysterious grey area in the centre is serving. Worse, this chart might injure you physically. Extended reading requires a chiropractic adjustment, thanks to the rotated labels. The liberal use of bright, saturated red matches the hue of the report’s cover but is the equivalent of UPPER CASE SHOUTING.
How could this be turned into a useful chart?
First, scaling. Why does the GPI start at 0.82 and finish at 1.12? There is of course just one reason — it is the default of the software used to create the chart.
The GPI is actually a measure of gender bias in access to primary education, with a value of 1 denoting no bias (equality) between boys and girls. So we should really anchor the bars to 1 and represent deviations from this central point by pushing the values above and below 1 in opposing directions.
This allows us to re-orient the chart, making the country labels easier to read. Simple text labels help confirm the shape and direction of the data to the reader.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2Fa3eaaf48-d128-11e7-b781
Next we can re-introduce the mysterious grey shaded area. It is actually Unesco’s performance target. This is essential information because it allows us to place each country’s performance in context.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2Fb35fd52a-d128-11e7-b781
We can bring back colour, this time to draw attention only to the countries that are not meeting the Unesco target. Distinct colours make it clear there are two different reasons for not hitting target. On-chart annotations concisely reinforce the main message.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2Fc57652de-d128-11e7-b781
Finally, clear titles help non-specialist readers tune in to a chart. Technical details can be relegated to the subtitle and footnotes — such as the source. It is important information, but not necessarily the first thing the reader should see.
▻https://www.ft.com/__origami/service/image/v2/images/raw/http%3A%2F%2Fcom.ft.imagepublish.prod.s3.amazonaws.com%2Fd54bf36c-d128-11e7-b781
If we compare the original and the rework, it is difficult to see how we are looking at the same data. Where Pakistan was previously barely noticeable, now its bias against girls becomes the standout story.
In fact, it is only by reworking the chart that we can see it is of any use at all. Many charts cannot be transformed in this way. Adopt a “fewer but better” mantra when it comes to incorporating them in reports.
With well-selected charts taking care of the key questions of “what?” and “how much?”, the text in a report can focus on the follow-on questions, such as “why?” and “so what?” By conceiving words and graphics simultaneously, reports can be restructured into readable and confident narratives.
The willingness shown by Unesco to critique and improve its materials is also important. No amount of external consulting will achieve lasting improvements in quality unless the desire to improve is at the heart of an organisation.
This may sound deceptively straightforward but communicating with data is a skill that has fallen through gaps in academic curriculums. Few receive formal training.
In January 2018 we are inviting readers to the Financial Times for a one-day introductory Chart Doctor workshop on effective data presentation. More details and booking information are available via Eventbrite.
In the meantime, we would like to hear from FT readers about the business charts that rile you most. We have opened up comments below for you to upload your own favourite bad graphics. Do your worst.

Un phénomène nouveau né à San Francisco commence à essaimer dans les villes occidentales : la révolte des Yimbys (d’après l’acronyme yes in my backyard, qui signifie “oui dans mon jardin”). Ce nom de code désigne les trentenaires, diplômés, qui peinent à se loger. Ils se mobilisent pour réclamer à leurs aînés la construction de tours d’habitation. Et tant pis si cela implique de détruire quelques potagers.

ANCIENT GREEK GEOMETRY
▻https://sciencevsmagic.net/geo
What can you make using only circles and straight lines? Yes, you can cut a pie into a million slices, but when you’ve got to make the pie yourself using only two dots as your starting point, the challenge becomes much greater. That’s the basic idea behind Ancient Greek Geometry, a webtoy by Nico Disseldorp that uses basic mathematical principles to spin basic drawing into an intriguing puzzle.
Ancient Greek GeometryYour only two tools when playing with Ancient Greek Geometry are a straightedge and a compass (the kind that looks like a giant pair of tweezers, not like a GPS’s compass). Starting with two given points, you can build your design by drawing a line between two points (click and drag to connect them), or a circle that has one point as its center and another point along its circumference (click and drag to the appropriate radius). Believe it or not, you can construct a lot of shapes with these techniques, including triangles, squares, and the elusive pentagon. This webtoy gives you the choice of tackling these shape challenges within the suggested numbers of moves, or freely building your own designs. How complex you get is entirely up to you in this intriguing diversion.

Je viens juste de découvrir le site et la graphiste Anna Vital.
The key to communicating visually is finding ubiquitous visual symbols that need no verbal explanation.
Most research in cognitive science explores how we see things but little research is done on how we understand what we see.
Understanding is the ultimate test of how good your visualization is. So how can you make people understand? Show something familiar and analogize. If you know nothing else about visualization but pick the right analogy you are more than half way there. This is what a professional designer does – and there is no substitute for analogies.
Connected Scatterplot
▻http://steveharoz.com/research/connected_scatterplot
As far back as the 1790s, the connected scatterplot was used to visualize the cycle of a steam piston. Economists have since used it to depict data about unemployment and job openings over time.
Recently, journalists have begun using the technique to convey information to readers. But how well do those readers understand this unfamiliar format?
What the numbers say about refugees. The biggest concentrations of displaced people lie far from the spotlight.
Growing concerns over an ‘invasion’ of refugees and migrants helped to elect Donald Trump and sway Brexit voters. Yet the data suggest that the situation is very different from how it is often portrayed.
Researchers warn that misleading reports about the magnitude of flows into Europe and the United States are creating unjustified fears about refugees. That is undermining efforts to manage the massive humanitarian problems faced by those fleeing Syria and other hotspots.
The number of refugees and migrants entering the European Union is low compared with the bloc’s population. Nations in Africa and Asia are absorbing many more. “The number of refugees in Europe is a classic example of perception versus reality,” says geographer Nikola Sander at the University of Groningen in the Netherlands.

Data on movements of refugees and migrants are flawed
Data and statistics must be handled with care. The pages of this journal — and thousands of others — are filled with reports and analyses that are only as strong as their weakest data set. So when the European Union’s border guards issued an exaggerated estimate of migration figures for the first nine months of 2015, it’s perhaps no surprise that it was an academic who called them out.
