{"version":"1.0","type":"rich","title":"Activity7_Q2","description":"This area chart visualizes total movie ratings aggregated by genre, using a dataset loaded from a GitHub-hosted CSV file via `d3.csv`. The chart displays each genre on the x-axis with a rotated-axis label and total ratings on the y-axis, rendered as a filled purple area path generated with `d3.area()`. Circles mark each data point and reveal a tooltip on mouseover. The visualization employs `d3.rollup` to sum ratings and `d3.scaleBand` and `d3.scaleLinear` for axes, with SVG rendering and animated tooltip transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55c7f2f55197476685bdee931aaa40a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
