This choropleth map visualizes cervical cancer case rates per 100,000 inhabitants across US states in 2018, with a color legend and hover tooltips revealing exact case counts, populations, and rates for each state; states with missing data appear black. The visualization uses D3 v6 with `d3.geoPath` to render TopoJSON state boundaries from the us-10m dataset, while a `d3.scaleQuantize` and the d3-legend library generate the color scale. Tooltips are positioned dynamically based on cursor location, and CSV data is loaded via `d3.csv`.
