{"version":"1.0","type":"rich","title":"Activity7_area_chart","description":"This area chart visualizes monthly sales data for electronics, clothing, furniture, and toys across four smoothed, semi-transparent colored areas. It loads CSV data from a GitHub gist using `fetch` and `csvParse`, then renders an SVG chart using D3 v5. The visualization employs `scaleBand` and `scaleLinear` for axes, `area` with `curveBasis` for smooth paths, and `axisBottom`/`axisLeft` for ticks. A legend maps each category to its fill color, with styling defined in external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/91d7f1bfdddb45dd9f52a2c50390cbab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
