{"version":"1.0","type":"rich","title":"Choropleth Map, COVID, Ohio","description":"This choropleth map visualizes COVID-19 case counts across Ohio counties, using a yellow-to-red sequential color scale to encode the number of cases per county. The map renders SVG paths via `d3.geoPath` with a Natural Earth projection, drawing county boundaries from World Atlas TopoJSON and overlaying graticules and land features. React manages the component state, while D3 modules (`scaleSequential`, `schemeYlOrRd`, `csv`, `json`) load the data and compute the color mapping. The visualization shows case data from a CSV hosted on GitHub, with the color scale domains set dynamically based on the maximum case count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/592f8a4389ba4e648fcd23843c835eef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
