{"version":"1.0","type":"rich","title":"Fork of Portland Map","description":"This visualization renders a map of Portland neighborhoods as a choropleth of vector paths. The code uses d3.geoConicEqualArea with a custom projection and d3.geoPath to draw the geographic features, while topojson’s feature method extracts the neighborhood boundaries from a TopoJSON file. The React component loads the data asynchronously and displays the SVG paths with a teal stroke, sourced from the Data Canvas Sense Your City dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/223b12863c624752bcf972ef995d4033?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
