{"version":"1.0","type":"rich","title":"act6 q2 ","description":"This example shows a stacked bar chart of sales by category across four quarters, with tooltips revealing exact values per segment. It uses D3 v7’s `d3.stack`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisLeft`/`axisBottom` to render an SVG. The code loads data from a local CSV, applies an ordinal color scale, and builds an interactive hover tooltip with D3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db7793d32d0f4c3cae14c6ff6cf5305c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
