{"version":"1.0","type":"rich","title":"US Choropleths Map And Captital/Major Cities","description":"This example displays a choropleth map of the contiguous United States with state boundaries rendered as colored polygons, overlaid with two city datasets. State colors transition from white to blue via a `scaleLinear` color scale, while graticules and interior borders are drawn using `d3.geoPath` and `d3.geoGraticule`. Population data from a world cities CSV appears as semi-transparent purple circles sized with `scaleSqrt`, and state capitals from a Vega JSON file are fixed black dots. The map uses TopoJSON from the us-atlas library, projected with `geoAlbers` in an SVG rendered through React.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
