{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map visualizes passenger counts by country with a green color scale, showing geographic distribution of aviation traffic. The visualization uses D3 v5's geoNaturalEarth1 projection and geoPath to render world map data from world-atlas TopoJSON, while CSV data provides country codes and passenger values. Countries are colored using scaleOrdinal with schemeGreens, and interactive zooming is implemented via D3's zoom module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5095d0bedb7e48a29080543357bf0dcf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
