{"version":"1.0","type":"rich","title":"World Map D3","description":"This example displays two choropleth maps: global country-level and US state-level average temperatures, colored with a sequential RdYlBu scale. It loads GeoJSON features from TopoJSON files via `topojson.feature` and maps temperature data from a CSV using `d3.rollup` to compute means per country and city. The world map uses a `d3.geoNaturalEarth1` projection, while the US map uses `d3.geoAlbersUsa`, both rendered as SVG paths via `d3.geoPath`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e4d8c586f09442dac7eeb3905f48086?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
