{"version":"1.0","type":"rich","title":"Mass Map 2","description":"This example renders a choropleth map of Massachusetts using the Albers equal-area conic projection. It displays the state’s geographic boundaries as SVG paths, colored with a teal stroke and fill. The visualization uses React to manage state and rendering, calling `d3.geoPath` with `d3.geoAlbers` to project the GeoJSON data fetched from a GitHub gist via `d3.json`. The `topojson` library’s `feature` function converts the TopoJSON structure into GeoJSON features for plotting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe619d7258db44bbad4be600ead24208?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
