{"version":"1.0","type":"rich","title":"Portland Map","description":"This visualization displays the neighborhoods of Portland, Oregon as a choropleth-style map using a conic equal-area projection. The map renders geographic boundaries as SVG paths generated with `d3.geoPath` and `d3.geoConicEqualArea`, with the data loaded as TopoJSON and converted to GeoJSON features using the `feature` function from `topojson`. The React application fetches the neighborhood data from a GitHub Gist and renders each boundary with a consistent teal stroke, creating a clean, minimalist view of the city’s districts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74c5b8c3a97c4f7f8b44a534cc8d3d43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
