It renders SVG paths via `d3.geoPath` and TopoJSON data from `us-10m.v1.json`, while county values are loaded from `education.csv` and mapped with `d3.map`. The color scale employs `d3.scaleThreshold` and `d3.schemeBlues[9]`, with county tooltips showing exact percentages and state boundaries drawn as white strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/283a1a1c87474d0c973baef3beecaa71?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
