This interactive map visualizes U.S. home price performance by state, using color to encode the seasonally adjusted 1-year metric, alongside major cities sized by population. The D3.js v7 code loads TopoJSON from us-atlas and GeoJSON data, projecting paths with d3.geoPath and a geoAlbersUsa projection. Animated hover effects reveal detailed state metrics and city statistics (median home price, rent, income) via a custom tooltip, while distinguishing state choropleth shading from proportional city circles in a single SVG rendering.
