{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the distribution of total earthquakes across US states using a diverging color scale. The map is rendered as an SVG using D3.js and the `geoAlbersUsa` projection, with state boundaries drawn via `geoPath`. Earthquake counts are logarithmically transformed and mapped to a threshold color scale from the `schemeOrRd` palette, while hovering highlights states in light green. The data is loaded from CSV and TopoJSON files, and tooltips display state name, region, and raw earthquake totals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d01e2d2fed2a4a1787e5e3cc14f07162?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
