Bar chart race example: economic power over 400 years

The animation follows the changing rank of major economies across roughly four hundred years. Because the bars re-order continuously, the viewer can see the balance of power shift rather than just compare two endpoints.

That is where a bar chart race earns its keep. The format is strongest when the ranking itself is the story and when long time horizons would otherwise feel abstract.

This example also shows why bar chart races work well for editorial and educational publishing. Viewers do not need to know the whole dataset in advance. The motion teaches them how the hierarchy changes.
