{"version":"1.0","type":"rich","title":"Fork of USA Map 2","description":"This interactive map shows US state home price performance as a choropleth, colored by seasonally adjusted one-year returns, alongside city markers sized by population. Hovering reveals detailed tooltips for both states and cities. It uses D3.js v7 with `d3.geoAlbersUsa` and `d3.geoPath` to render TopoJSON state boundaries, plus `d3.scaleSequential` for color encoding and `d3.scaleSqrt` for circle sizes. Data comes from two CSV files covering state-level price indices and city-level housing metrics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6dea3bc7f94245579f9cffd5775dd53f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
