{"version":"1.0","type":"rich","title":"Activity6_Task2_lets_go","description":"A stacked bar chart displays the percentage distribution of letter grades (A through F) across six classes. The code uses D3 v7 with `d3.stack` and `d3.scaleOrdinal` to construct the visualization. Tooltips reveal exact percentages on mouseover via `d3.select` and HTML injection. The chart renders as SVG, sourcing data from a local CSV file, with custom margins and axes created through `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c03cf1aeeb94750998f32135342d02b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
