{"version":"1.0","type":"rich","title":"Fork for NYC ex","description":"This choropleth map displays COVID-19 test positivity rates across New York City ZIP code tabulation areas, with gray indicating missing data. Built with React and D3 v5, it uses `geoEquirectangular` and `geoPath` to project boundaries loaded via TopoJSON, while `scaleThreshold` and `schemeBlues` map the percentage values. Hovering highlights a region and triggers a callback with the underlying data. The visualization combines NYC MODZCTA boundary data with COVID and income statistics from gist-hosted sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00eaa340360c4202bf495f8b9652fb18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
