The Washington Post: U.S. life expectancy |
Those were my thoughts when I visited a recent interactive visualization by The Washington Post's graphics desk (Twitter.) Everything works nicely for me here: The layout, the composition, made of different kinds of charts and maps —choropleth map, time-series graph, a truncated slopegraph on the bottom-right,— the copy, the visual style, and the simple interface.
As I've explained before, one of the main exercises that I ask my students to do at the beginning of each semester is to comment on published infographics based on their efficiency, functionality, design, the insights that they facilitate, and other criteria. This is easy to do if the instructor chooses deeply flawed graphics from an infographics mill, but it's much trickier when the task is to review an excellent project.
So here's some summer homework for you: Explore the interactive, read the story —otherwise, you won't understand what the focus is— and think: a) Are there other ways to display these data? b) Are we missing variables which could make the core messages clearer? c) How should those variables (both the ones included and the ones that we could potentially add) be visually compared and related to each other? I don't have answers to those questions myself —well, perhaps I do, but that's the point of the exercise, isn't it?
