{"version":"1.0","type":"rich","title":"Question 2","description":"A stacked bar chart visualizes sales performance by region, breaking down percentages across four product categories using data from a local CSV file. The chart employs D3 v7's `d3.stack` and `d3.scaleBand` to render SVG rectangles, with a tooltip triggered by mouse events. An ordinal color scale maps categories, and axes display percentage values. The static title and legend complete the presentation, showcasing local module imports alongside the D3 library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb1c615b29df40a58746baf06e6cd927?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
