{"version":"1.0","type":"rich","title":"question_1","description":"This pie chart shows the distribution of insurance records across four regions—southeast, southwest, northeast, and northwest—using data loaded from an external CSV file. The chart uses D3 v7’s `d3.pie`, `d3.arc`, and `d3.rollups` to aggregate and visualize the counts, with a categorical color scale (`d3.scaleOrdinal`) assigning distinct colors. Each slice is labeled with its region name via arc centroids, and a legend is rendered using SVG rectangles and text elements, all positioned within a 600x600 SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d23bea1290e744e09a50d2319a638912?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
