Quantile Choropleth
This choropleth map shows 2023 median home prices across New York State counties, colored with a quantile scale divided into five classes using `d3.scaleQuantile` and `d3.schemeBlues`. County polygons are rendered with `d3.geoPath` and a Mercator projection fitted to the state, with tooltips revealing median prices and sales counts. The visualization loads TopoJSON geography and CSV housing data, and includes a legend displaying threshold values. It uses D3 v7 for all data binding, map rendering, and interaction.
