{"version":"1.0","type":"rich","title":"Barchart","description":"An interactive stacked and grouped barchart displays multiple data series generated by the `bumps()` function in `testdata.js`. The chart’s primary view is a stacked barchart, with a radio-button form allowing the user to toggle the layout to a grouped barchart, triggering an animated transition. The visualization uses D3 v6 scales, including `scaleBand` and `scaleOrdinal`, and a `d3.stack` operation to compute the stacked series. An SVG tooltip, populated with a legend of series values, appears on mouseover events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a9c2f0448c4486382ec86df0a31df4c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
