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.
