This infographic video from The Economist looks crisp, sensible and appealing, but I am left wondering a few things:
1) Why they would choose a radial chart for something that’s not periodic?
2) What advantage does this format have over a linear timeline/fever chart with callouts and tooltips? Do we need to watch the line moving in real time?
3) Why use video rather than interactive UI?
Any thoughts on this? Please share.
