Fork of D3 Starter-likitha
✓ Published0🌍 Public
This pie chart visualizes the regional distribution of bird migration records from a sample CSV dataset. The chart uses D3.js v7 to load the data via `d3.csv`, aggregate counts per region, and render SVG arcs with `d3.pie()` and `d3.arc()`. Labels are placed at arc centroids, and a color legend assists interpretation. The visualization employs `d3.scaleOrdinal` with `schemeCategory10` for distinct regional colors.
