This example visualizes the prevalence of stunted children across eight blocks in Palghar, India, using a dot-density map. It displays the geographic boundaries of each block, filled with a texture pattern that varies based on the percentage of stunted children, and includes an interactive slider to filter the data range. The visualization uses D3 v5 with `d3.geoMercator` and `d3.geoPath` to project GeoJSON boundaries, while the `textures` library generates circle and line patterns for the fills. A tooltip appears on mouseover to show the block name and its stunted child percentage.
