{"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 per U.S. county using a blue threshold color scale and a legend with tick marks. The code loads education data from a CSV and U.S. county boundaries from TopoJSON via `d3.json` and `d3.csv`, then renders paths with `d3.geoPath`. It uses `d3.scaleThreshold` and `d3.schemeBlues` for coloring, adds hover tooltips via SVG `<title>` elements, and overlays state boundaries with `topojson.mesh`. The visualization is built with D3 v5 and React, drawing to an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e85993cdc3854286be1ebaf96acd077d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
