Alors : un long portrait de celui qu’on appelle le gourou de la visualisation, Edward Tufte. A lire et à discuter.
One day in the spring of 2009, Edward Tufte, the statistician and graphic design theorist, took the train from his home in Cheshire, Connecticut, to Washington, D.C., for a meeting with a few members of the Obama administration. A few weeks earlier, he had received a phone call from Earl Devaney, a former inspector general in the Department of the Interior, who is best known for leading that agency’s investigation of the lobbyist Jack Abramoff. Devaney had recently been appointed head of the Recovery Act Accountability and Transparency Board, the body created by the Obama administration to keep track of the $780 billion in federal stimulus money that has spread out across the country.
Whereas Devaney once led a team of professional investigators responsible for sniffing out waste, fraud, and abuse, he was now faced with a rather different, but related, task: designing a Web site. In the stimulus bill, Congress had called for the creation of “user-friendly visual presentations” of data that would allow the American public to watch over the disbursement of the giant funding package. This wasn’t exactly familiar territory for Devaney, a career lawman. Perhaps Tufte could offer some advice?

How Useful is Tufte for Making Maps? | Making Maps: DIY Cartography

Edward Tufte’s The Visual Display of Quantitative Information (1998, 2nd edition 2001) is a classic book, arguably his best, and certainly a key text in the field of information graphics (which encompasses cartography). I know some cartography courses use the book as a text.
I recall being inspired by the book as a neophyte cartographer back in the late 1990s.
The book looked great: its design communicated the importance of design (when most other cartography and information graphics books were clunky and poorly designed). The tone was serious and high-minded: I was designing information graphics. And I think I absorbed Tufte’s minimalist design philosophy, although cartographic design, at least the way I learned it, was largely minimalist, with no allowance for flourish, fake 3D embellishment, or other chartjunk (or “map-crap” as I call it in the Making Maps book).
How PowerPoint is killing critical thought | Andrew Smith | Comment is free | The Guardian

still remember the best lecture I ever attended. It was part of a joint series offered by the English and philosophy departments in my first term at university and, given that the subject was Sartre’s Being and Nothingness, should have been the dullest event in Christendom that night. But it wasn’t. The lecturer, Thomas Baldwin, had a deceptively simple style: he would write a proposition on the blackboard facing us and gaze at it for a moment, like a medium beckoning a spirit. Then he would turn and smile, and start to explain.
“Did the lecturer use PowerPoint?”
“Hm. No, he just spoke,” she said.

Enquête sur ce logiciel qui rend stupide

Je vais rabâcher sans doute mais c’est un outil, ni plus ni moins. Je m’en sers souvent (enfin, son équivalent LibreOffice Impress) mais c’est un support pour moi, rien de plus. Ça me permet juste d’afficher un genre de fil directeur pour la mnémotechnie (pour ma mémoire quand je parle, et pour fixer dans l’esprit de mes auditeurs qui auraient une mémoire plus visuelle).
Cela dit c’est très bien vu ça :
Where the space around and between points on a blackboard is alive with possibility, the equivalent space on a PP screen is dead. Bullet points enforce a rigidly hierarchical authority, which has not necessarily been earned. One either accepts them in toto, or not at all. And by the time any faulty logic is identified, the screen has been replaced by a new one as the speaker breezes on, safe in the knowledge that yet another waits in the wings. With everyone focused on screens, no one – least of all the speaker – is internalising the argument in a way that tests its strength.
… et ça me calme radicalement.
A mon travail je suis en train de devenir connu pour être le type qui explique des trucs avec un tableau. Ce qui m’amuse c’est la tête des gens qui arrivent à mes présentations dans une salle vide et sans vidéo projecteur. Leur tête quand ils comprennent qu’en fait c’est tout simple, pas besoin de copies d’écran, il suffit juste de dessiner des rectangles et de les relier entre eux en même temps qu’on explique ce qui les relie.
Ce qui les amuserait encore plus, ce serait de me voir essayer de créer une page de powerchose (ce que je ne sais absolument pas faire et refuse même d’apprendre à faire).

The Cognitive Style of Powerpoint: Pitching Out Corrupts Within
In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now “slideware” computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
Edward #Tufte Wants You to See Better

LICHTMAN: Is there a data that - sorry - is there a #data that can’t be #visualized well?
TUFTE: Not if you allow #artists into the arena.
Il a tort : les artistes font mille fois mieux que les vrais cartographes :) (et je sais de quoi je parle).
comme #jacques_bertin qui était génial, #tufte sait qu’il st considéré comme une sorte de #gourou de la #visualisation et ça ne le rend pas du tout modeste.
Bertin est arrivé au « Monde » dans les années 1980 en expliquant au cartographe de l’époque, Robert Second, que sa carto c’était vraiment de la merde. Robert Second, qui était vraiment sympa, en a gardé une grosse douleur dans l’âme, et aucun des étudiants de Bertin n’ont pu faire de stage au journal pendant les 25 ans qui ont suivi ! Bertin n’a pas vraiment aidé à améliorer le dialogue avec les cartographes de presse... :)
@Reka : l’impression que ton commentaire dit l’inverse de lui : il dit bien que tu peux faire de la bonne visualization de tout si tu travailles avec des artistes, non ?
Ah que c’est drôle, j’avais interprété sa phrase exactement à l’opposé ! ha ha !
On est peu de chose...
et je trouve que si effectivement #tufte n’est pas très modeste il prend toujours soin de mettre en avant des choses qu’il a vu ailleurs en prenant soin de citer les personnes
Oui, mais même, je suis pas un grand fan de ses méthodes

Edward Tufte forum: Slopegraphs for comparing gradients: Slopegraph theory and practice
▻http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0003nk
write a program posted on github or as a Chrome app whose output closely replicates the (1) GNP slopegraph and the (2) cancer survival slopegraph immediately below. Necessary subtleties include thin gray lines that don’t crash into words/numbers, typeface Gill Sans or equally refined, tuned ordinal spacing of words at left the
line paths, probably best to make each line graph separately and then order and stack them appropriately to avoid too many line crashes. The idea is to compare slopes, with what are in effect a set of separate plots then ordered by first entry and then stacked with
some optical care.

Edward Tufte is the guru of graphics, the high priest of presentation. For more than 30 years he has been showing us how to visualise data with simplicity, clarity and elegance, while campaigning against “chartjunk” and other design practices that lead to obfuscation.
Tufte, 71, was born in Kansas City, Missouri and grew up in Beverly Hills, California. He started his academic career as a political scientist at Princeton University and moved seriously into data visualisation in 1975. He was prompted by a request to teach a statistics course; the low standard of statistical graphics available in the literature made him realise that he could do better himself.
