{"version":"1.0","type":"rich","title":"activity6_question2","description":"A stacked bar chart displays TV brand ratings across five percentage categories (below 2.0 to above 6.5), with each bar segmented by brand. The visualization loads data from a CSV file and renders SVG using D3 v7. It employs `d3.stack()`, `d3.scaleBand()`, `d3.scaleLinear()`, and `d3.scaleOrdinal()` to position and color segments, while mouseover events trigger a custom tooltip showing exact rating percentages.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e50520df48d4f20b7eab8f85edc858f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
