This interactive housing dashboard visualizes New York State county-level housing metrics alongside a U.S. city comparison map, supporting exploration via a year selector and county click-filtering. It renders a choropleth map of counties using TopoJSON geo data and `d3.geoPath`, with circles scaled by population and colored by median home price on a separate U.S. map. Linked bar charts and line charts update based on selections, making use of D3's scales, axes, and selection methods. The dashboard displays data sourced from a CSV containing sales counts and median prices for 2022–2024.
