{"version":"1.0","type":"rich","title":"World Choropleth","description":"This interactive choropleth visualizes world countries, colored by economy type and labeled with country names. A hover tooltip displays each country's population, GDP, income group, and continent. The map uses D3's `geoNaturalEarth1` projection and `geoPath` for rendering, with TopoJSON for geographic data. Zoom and pan are enabled via D3's `zoom` behavior, while a categorical color legend uses `scaleOrdinal` with the `schemeSet3` palette to differentiate economy categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c7d5b46662a4dd6aa7ddc8ca116a6d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
