This D3.js visualization displays the 2018 populations of Indian states as a pie chart, with each state represented by a colored slice sized according to its ranking value. The chart is rendered as SVG using D3’s `pie`, `arc`, and `scaleOrdinal` APIs, with data fetched as CSV from a GitHub gist. Slice labels and a legend show population figures formatted in thousands using `format`, while the overall layout is fixed within an SVG canvas of 960×500 pixels.
