{"version":"1.0","type":"rich","title":"Mapping vehicle pollution and vegetation removed pollution in USA","description":"A choropleth map of the United States displays the net effect of vehicle pollution versus the pollution removed by vegetation for each county, with a sequential blue-yellow-red color scale indicating the balance. The visualization uses D3.js v4 with the `d3.geoAlbersUsa` projection and `d3.geoPath` to render county boundaries from Census Bureau data, while an animated bar chart details the pollution contribution for a hovered county. The map is interactive, supporting zoom and pan via `d3.zoom()`, and color encoding uses the `d3.interpolateRdYlBu` scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e26f6f94e787499e8d4d509968660e72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
