A bar chart race is an animated sequence of bars that show data values at different moments in time. The bars re-position themselves at each time period so that they remain in order (either ascending or descending).

The trick to making a bar chart race is to transition the bars slowly to their new position when their order changes, allowing you to easily track the movements.

For this bar chart race, we’ll use a small dataset produced by John Hopkins University containing the total deaths by date for six countries during the currently ongoing coronavirus pandemic. Let’s read it in now.
