This example displays a choropleth map of eight blocks in Palghar district, India, using SVG paths rendered via `d3.geoPath` with a `geoMercator` projection. The map shows the percentage of stunted children per block, with fill patterns generated using the textures library and a slider to adjust classification thresholds. A tooltip appears on mouseover, and zooming is enabled through `d3.zoom`. Data is loaded from a CSV file and joined to GeoJSON features.
