{"version":"1.0","type":"rich","title":"Fork of CO2 emissions bubble chart ","description":"This interactive map visualization displays unemployment rates across U.S. states, using a blue sequential color scale where darker shades represent higher percentages. Built with D3.js, the code loads state boundaries from GeoJSON via topojson-client, applies the geoAlbersUsa projection, and renders paths using d3.geoPath with fill colors assigned through d3.scaleQuantize. A legend automatically generates color-to-value mappings using the invertExtent method, while the chart title and margin-based layout structure the composition. The visualization demonstrates choropleth mapping with data-driven styling and interactive SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e64784b98ed84da5967b9b1af5ca5b23?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
