{"version":"1.0","type":"rich","title":"Choropleth Map of County Data","description":"This choropleth map colors U.S. counties to visualize geographic data, with state boundaries drawn as white lines for contrast. The map is rendered as SVG using `d3.geoPath` to project TopoJSON geometry onto a 960×600 canvas. County and state shapes are styled via CSS classes, with the d3-scale-chromatic library available for color encoding. A small script sets a tooltip title on the label element, though the map itself does not display interactive data values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc890d67dcc64affa5a2caab27afb7f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
