{"version":"1.0","type":"rich","title":"Fork of A9: D3 Choropleth Map","description":"This interactive choropleth map visualizes county-level real estate metrics across New York, allowing users to compare median home prices or sales counts for 2022–2024 via dropdown menus. Hovering a county reveals its specific value in a tooltip. The visualization uses D3 v7 with `d3.geoPath` and `d3.geoAlbers` to project TopoJSON boundaries from the US Atlas, while `d3.scaleQuantile` drives a color legend. County colors transition smoothly between selections, and counties lacking data appear gray.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a2a92ee35f34330a3c0d5d22602a352?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
