{"version":"1.0","type":"rich","title":"Fork of  Assignment 9: Choropleth Map","description":"This choropleth map displays the percentage of adults with a bachelor’s degree or higher across U.S. counties, using a blue color scale to show geographic variation. The visualization renders county boundaries as SVG paths via `d3.geoPath` and `topojson`, with state outlines overlaid. It loads data from `education.csv` and the `us-10m.v1.json` TopoJSON file, mapping each county’s FIPS code to its value. A color legend with an axis indicates the percentage ranges, and tooltips show county names and exact values on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4752cd791b1467796ba645733f7ad34?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
