{"version":"1.0","type":"rich","title":"Choropleth Map with interactive filtering","description":"This choropleth map visualizes countries' economies using color-coded paths, with an interactive legend that filters the map by economic classification. Clicking a legend category dims non-matching countries and highlights those selected, while a semi-transparent sphere provides geographic context. Built with React and D3 v5, the example uses `geoPath` with the `geoNaturalEarth1` projection for rendering SVG paths, `scaleOrdinal` and `schemeSpectral` for the color scale, and `zoom` for pan and zoom interactions. Data is loaded from the world-atlas package and processed via `topojson.feature`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/064474ecf526440b992f590296c6d998?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
