Bar Chart Race

Make a bar chart race from CSV data and watch the categories reorder over time. Play it fullscreen. Your data stays local.

How It Works

1

Load your CSV data

Paste CSV data or upload a file, then click Load Data. First column is the time label, remaining columns are named data series with numeric values.

2

Play the animation

Hit play to watch bars compete and reorder as values change over time. Adjust speed, max visible bars, and color palette.

3

Present it fullscreen

Press f or the fullscreen button for presentations, with keyboard controls (Space, arrows). There is no export: screen-record the fullscreen view to keep a video.

FAQ
