{"version":"1.0","type":"rich","title":"Fork of PM 2.5 Particle Change in US","description":"This interactive map displays PM2.5 particle concentrations across US counties from 2000 to 2018. A slider and play button animate through yearly data, with a sequential YlGnBu color scale mapping concentration values. The visualization uses React with D3 v5’s `geoPath` and `geoIdentity` projections to render county boundaries from TopoJSON data, while county-level PM2.5 values are loaded from a CSV file. Hover tooltips reveal state and concentration details, and the color legend provides axis ticks for reference.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71dda15eb79f4b72ac613db4fca41527?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
