This pie chart visualizes the populations of ten Indian states in 2000, with each slice’s area proportional to its population value and a legend mapping colors to state names and exact counts. Built with D3 v5, it loads JSON data via `d3.json`, arranges arcs using `d3.pie()` and `d3.arc()`, and assigns categorical colors through `d3.scaleOrdinal` with `d3.schemeCategory10`. The SVG rendering includes text labels formatted with `d3.format`, while the legend is manually constructed using appended rectangles and text elements.
