This interactive map visualizes seasonally adjusted home price performance across U.S. states, using color intensity to show one-year price changes, while city-level circles sized by population reveal housing metrics like median prices and rents. Users hover over states and cities to access detailed data. The visualization uses D3 v7 with a `d3.geoAlbersUsa` projection and `d3.geoPath` to render TopoJSON state boundaries, alongside `d3.scaleSequential` for color coding and `d3.scaleSqrt` for circle sizing.
