{"version":"1.0","type":"rich","title":"ICE-06: Bar Chart","description":"A bar chart visualizes total revenue by product category, with each bar’s height and color mapping to aggregated sales data and category identity. The D3 v7 code loads a CSV from a GitHub gist, rolls up rows by category using `d3.rollup` and `d3.sum`, then renders SVG bars with `d3.scaleBand` and `d3.scaleOrdinal`. Axes, value labels, and chart titles are added via D3 selections, while the React wrapper only displays static text and does not participate in the chart rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2aa7fd5eb7114f4bab405f1412b1c331?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
