Animated graphs, part III

This is a continuation of Animated graphs, part II
I’ve talked the last two weeks about a series of animated, interactive graphics used by Hans Rosling to illustrate the differences, and surprising similarities, between the global “haves” and “have nots.” The first week, I showed how a little animation can make great graphs. The second week, I analyzed Rosling’s progression from simple graphs — which give the audience a framework for understanding — to complex, nuanced analysis of reality. Rosling uses animation to build upon his previous graphs for a seamless interaction with the audience
In this final installment, I look at just the following slide, in which Rosling shows not only the child survival rate and GDP per capita for each of 200 countries in the world, but he also displays data by quintiles for five African countries.

This is a continuation of Animated graphs, part I
Last week I began an analysis of the images Hans Rosling uses in his presentation on the relationship between the global “haves” and “have nots.” In particular, his focus is on how people’s conceptions of the global North and global South (different terminology for the same concept of haves/have nots) may have been an accurate reflection of reality at one point in history, but may not be accurate today.
To make his case, he relies on a few sets of time-series data which he presents to great effect in some animated graphics. One thing that I like about Rosling’s work is that he start simple to get his audience to understand what he is talking about. Then he builds in data to make the presentation more accurate and nuanced.
For example, he presents a graph here that compares child survival rates with per capita income. Circles toward the top show better chances for survival, while circles toward the right show wealthier countries. Rosling adds a very helpful label (“good” and “bad” for health) to explain the “survival” scale, which some readers may find cryptic:

This is the first in a three part series
I happened across this video on the TED.com network. In it, professor Hans Rosling demonstrates a number of good practices in conveying information to an audience in an understandable and innovative fashion.
It’s also quite enjoyable to watch him really interact with his data. The whole video is viewable here. It’s about 20 minutes long but quite worth it. What follows are a series of screenshots that explain some of the highlights of his techniques for information display.
1. This screen shows child survival as a function of GDP per capita. In other words, it answers the question: is there a link between how much money you make and health? The answer, viewable inthe graph below, is a clear yes, indicated by the linear progression of countries up the right hand side of the graph.
This is a clear graph, showing a lot of data in an organized fashion: mortality rates, GDP per capita and country population (the size of the bubble) are all visible. Notice all this data is for one year, 1962.
