United States Home Prices Map

Map of NY State County

This choropleth map of New York State counties visualizes median home sale prices for 2023, with each county shaded using a sequential blue color scale. Hovering over a county highlights its borders and displays a tooltip with the county name, median price, and sales count. The visualization uses `d3.geoMercator` and `d3.geoPath` to project TopoJSON county boundaries, `d3.scaleQuantize` for color mapping, and `d3.axisBottom` for the legend. Data comes from provided real estate sales records, with missing values shown in gray.

NY State Map 3 - working-Filtering Dashboard

This dashboard visualizes New York State housing market data from 2022 to 2024 across counties, featuring a choropleth map (d3.geoPath with a Mercator projection) colored by median home price, a bar chart of sales counts, and a line chart (d3.line) of price trends. Using D3.js, users select a year via dropdown to update all charts, and clicking a county on the map filters every chart to that county, highlighting selections in red. The bar chart shows the top 15 counties by sales when unfiltered, and the trend chart overlays lines for the top five counties by median price. Data is loaded from a CSV and processed through a custom `DataLoader` singleton that broadcasts updates to all registered chart listeners.
