{"version":"1.0","type":"rich","title":"Activity 7","description":"This pie chart visualizes the top 10 store areas by sales, using a dataset fetched via `d3.csv` from a GitHub-hosted CSV file. Slices are generated with `d3.pie()` and drawn as SVG paths using `d3.arc()`, with each slice labeled by its store area and sales value. A legend, built with SVG groups, maps the color-coded categories to their names. The chart uses a custom color scale from `d3.scaleOrdinal()` and is styled with a bordered SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e0d8f80106b4adda17149685bdc349d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
