{"version":"1.0","type":"rich","title":"Racing Bar Chart Animation Test","description":"A racing bar chart animation demonstrates changing quantitative values over time. Six named categories (alpha through foxtrot) increment their values by ten at random intervals, with each update triggering a smooth 750-millisecond transition of bar widths and labels using D3’s `select`, `scaleBand`, `scaleLinear`, and the `.join()` operation. Bars and text labels are rendered as SVG elements within a React component, driven by a custom `useInterval` hook that calls `setInterval` to update state. The chart uses D3 v5 and React, with data initially hardcoded in the app’s state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d4969f879124017926faf78749d6c6e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
