This choropleth map of India uses a sequential color scale to encode each state with a distinct category color and labels each state with its name. The visualization relies on TopoJSON data for Indian state boundaries, which is projected and rendered using `d3.geoMercator` and `d3.geoPath`. The code filters out the first feature from the dataset before drawing the SVG paths, applies `d3.scaleOrdinal` with `schemeCategory10` for fills, and positions text labels at path centroids using `pathGenerator.centroid`.
