{"version":"1.0","type":"rich","title":"Bubble Chart","description":"This bubble chart displays the locations and burn acreage of wildfires and prescribed fires across the United States from late 2019. The map uses an Albers USA projection via `d3.geoPath` to render state boundaries, while fire incidents are plotted as circles sized with a `d3.scaleSqrt` based on the ACRES field. Wildfires are filled in red, prescribed fires in green, and unknown types in white. The visualization includes a legend showing area scale examples and fire type colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/754612092c2b407f8fc939015b5e2906?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
