A choropleth of Ohio’s counties uses the state plane north projection, rendered as SVG paths. The map displays county boundaries and names sourced from the us-atlas TopoJSON, with hover highlighting in orange. The code calls `d3.geo.conicConformal` with custom parallels and rotation, then uses `d3.geo.path` and `topojson.feature` to draw shapes, automatically scaling and translating the projection to fit.
