{"version":"1.0","type":"rich","title":"D3 World Map","description":"This choropleth map visualizes the average university diversity index across U.S. states in 2021, using a white-to-blue linear color scale. Each state is rendered as an SVG path via `d3.geoPath` with a `d3.geoAlbersUsa` projection, colored by state-level data. Hovering reveals a tooltip, and a `d3.legendColor` legend displays the scale. The code loads TopoJSON state boundaries from a GitHub gist and uses D3 v4 and the d3-legend plugin.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e44620738ac48bda82949f0d3f82fb0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
