{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the economic classification of countries across the globe, using color to encode each nation’s economy category. The map is rendered with D3.js v5, using `geoNaturalEarth1` projection and `geoPath` to draw country boundaries. Country data is loaded from the world-atlas TSV and TopoJSON files, with the `economy` property mapped to a spectral color scale. Hovering over a country displays its name and economy type, while a custom color legend explains the color mapping. A zoom interaction is also implemented via `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51e392cb54274d7e806abf7928a29fd6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
