{"version":"1.0","type":"rich","title":"Choropleth map with Interactive Filtering in D3.js!","description":"A choropleth map of world countries colored by economic category supports interactive filtering: clicking a legend swatch dims all countries not in that category, with a highlighted stroke on the selected group. Built with React and SVG, the map uses `d3.geoPath` with the `geoNaturalEarth1` projection and `d3.scaleOrdinal` with the `schemeSpectral` palette. Data is loaded from the world-atlas TopoJSON and TSV files, and zooming is handled via the d3 `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d84d2850cfd145c68e9937e1a4b3da2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
