Bar Chart Race

A horizontal bar chart race. Each row is a competitor whose bar length maps to its current value, and the rows continuously re-sort as values change so bars slide past one another, with a number beside each bar that counts as it grows. Positions are computed with a logistic soft-rank so the reordering glides smoothly instead of snapping between slots.

Configure it through the RACERS array, where each entry has a label, a color, and a list of checkpoint values the chart eases between over the run. RACE_START and RACE_END set the pacing, BAR_H and ROW_GAP set the row density, and RANK_SHARPNESS controls how crisply near-tied bars separate. Motion is frame driven with interpolate() and a deterministic rank function, so preview and render match and the sequence ends on a stable final ranking. Use it for market share, sales by region, sports standings, or any ranking that shifts over a period.
