{"version":"1.0","type":"rich","title":"act7-q1","description":"This example displays a pie chart showing the distribution of insurance records across regions. It loads a CSV file from a GitHub gist and aggregates the data by region using `d3.rollup`. The pie slices are rendered with `d3.pie()` and `d3.arc()` into an SVG, with each slice labeled with its count and colored using `d3.scaleOrdinal` with the `schemeCategory10` palette. A separate legend SVG lists the region names and their corresponding colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c0e2c57465d4b41bf68409a06ddf5dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
