This pie chart visualizes the distribution of person types from a CSV dataset. It displays the count of each category as proportional slices, with text labels on each segment and a color-coded legend alongside the chart. The visualization is built using D3.js v7, employing the `d3.pie` layout, `d3.arc` for slice paths, and a group-based SVG rendering approach. A categorical color scale (`d3.scaleOrdinal`) maps person types to colors from the `d3.schemeCategory10` palette, and the data is loaded remotely via `d3.csv`.
