Endless River: An Overview of Dataviz for #Categorical Data
Let us explore some flow and network chart types that are ready-made for visual storytelling using categorical data As a data scientist, I am surrounded..
In summary, four types of charts for displaying flows between categorical data were discussed. Each chart type has its own unique quality for visual storytelling.
An Arc Diagram is useful at mapping 1:1 entity-relationships. Applications of such a chart include plotting the relationships of notes used in Beethoven’s Für Elise, to the character interactions in Les Misérables.
A chord diagram is used to display the strength of inter-relationships between categories. The thicker the chord, the stronger the relationship. One application of a chord diagram considers the relation between the count of words spoken between characters in the TV show Friends.
Sankey charts were shown to plot the multi-flow relationships between categories and can also be used to show the process flows between multi-component systems (e.g a steam engine)
Finally, a sunburst chart is used to plot event sequences and their proportional relationships as part of a wider set of relationships. Whether understanding the page-sequence flows on a website or the sequence of coffee flavours, a sunburst chart can cover it.
For all their differences, each chart types provides a unique way to tell a visual story with categorical data and their associated counts. Let the charts flow.

Daily chart: Measuring the arms merchants | The Economist
The countries that buy and sell the most weapons
FIVE countries—America, Russia, Germany, China and France—accounted for three-quarters of international arms exports over the past five years. China’s tripled its share in that time, overtaking France. It is on track to surpass Germany to become the third largest arms dealer. Business is brisk. Overall, sales between 2009 and 2013 were 14% higher than the previous five-year period, according to the Stockholm International Peace Research Institute, which tracks the arms trade. China sells to 35 mainly low- and middle-income countries, but is also a big importer (two-thirds of its weapons come from Russia). America exports to over 90 nations, with aircraft making up most of its sales. Russia exports more ships than any other country. Its weapons exports have significantly increased, thanks in part to being India’s biggest supplier, accounting for three-quarters of its arms purchases. As for Ukraine, it exports more weapons than Italy or Israel. But with regional tensions flaring, it may choose to keep some of those arms for itself.
