This choropleth map displays population density for census tracts in Maryland, using a color scale from `d3.scaleThreshold` and the `d3.schemeOrRd` palette. It shows how tract density varies across the state, with darker reds indicating higher densities. The visualization loads GeoJSON and population data via `d3.json` and `d3.queue`, then projects the tracts using `d3.geoConicConformal` and renders them as SVG paths with `d3.geoPath`. Density is calculated by joining population counts with tract land area from the GeoJSON properties.
