This interactive dashboard visualizes state-level home price appreciation across the United States, combining a choropleth map with a bar chart. Users can switch between four time periods (1 period, 1 year, 5 years, since 1991) using selector buttons. The visualization uses D3.js v7 (geoAlbersUsa, scaleBand, scaleLinear) within a React framework, rendering US states from a GeoJSON file and FHFA data loaded via d3.csv. Hovering over the map displays tooltips, while clicking states highlights them in both the map and bar chart simultaneously.
