{"version":"1.0","type":"rich","title":"US Wildfire map","description":"This interactive visualization combines a choropleth map of US wildfire burn areas with a stacked bar chart of fire causes. The map uses d3.geoRobinson projection and d3.geoPath to render state boundaries, with color encoding by total fire size and zoom-on-click functionality. A React-based bar chart displays fire counts by size class for selected states and years, with d3.scaleOrdinal color coding for causes. The Robinson projection and d3-scale-chromatic threshold scales handle the geographic and color mappings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3eaafdc6b8bf42028cb38029c11f19ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
