{"version":"1.0","type":"rich","title":"Fork of Portland Map","description":"This example displays a choropleth-style map of Portland neighborhoods, rendered as a single-color outline using a conic equal-area projection. The visualization uses React to manage the component lifecycle, with `useData` fetching TopoJSON from a GitHub gist and converting it to GeoJSON via `topojson.feature`. The `d3.geoPath` function, configured with `d3.geoConicEqualArea`, transforms the geographic coordinates into SVG paths, which are styled with a teal stroke. The map is centered on Portland’s coordinates and scaled to fit a 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/085db5b1cf5c40c2b49ecb1498941c9b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
