{"version":"1.0","type":"rich","title":"yi xiao Map","description":"This example visualizes earthquake totals across U.S. states by applying a logarithmic transform and mapping the results to an ordinal color scale with a sequential red scheme. The choropleth map uses `d3.geoAlbersUsa` projection, `d3.geoPath`, and TopoJSON state boundaries. Hovering highlights states in green. A color legend is rendered with `colorLegend.js` using `d3.scaleOrdinal`, and tooltips display state name, region, and raw earthquake counts. Data comes from a CSV of state earthquake records.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de34951d4c5d47fbaba571ce16955fd0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
