{"version":"1.0","type":"rich","title":"Fork of Fork of \n      United States Educational Attainment - Choropleth Map","description":"This choropleth map of the United States visualizes the percentage of adults aged 25 and older with a bachelor’s degree or higher, using a purple sequential color scale to encode educational attainment by county. County boundaries are rendered as SVG paths via `d3.geoPath`, with missing data shown in gray. A custom `d3.scaleThreshold` color legend displays class breaks, while mouseover interactions reveal county names, states, and percentages in a blurred tooltip. The visualization combines React components with D3 v5, importing data from FreeCodeCamp’s JSON endpoints for county boundaries and educational statistics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e1f7eb8e1b7f456f8e02ddaa2a03f164?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
