{"version":"1.0","type":"rich","title":"choropleth","description":"This choropleth map uses the Albers USA projection to visualize the number of earthquakes per state in the United States, rendered as Scalable Vector Graphics (SVG) paths. The map employs a threshold color scale with a sequential color scheme (OrRd) to encode the logarithmically transformed earthquake counts for each state. The visualization is built using D3's `geoPath` and `geoAlbersUsa` for projection and map generation, with `topojson` for feature extraction. Data is loaded from external CSV and TopoJSON files. Hovering over a state turns it light green, revealing tooltips with the region, state name, and earthquake count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/18c3f4b7a2f9478b8e5e4f6fef44a007?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
