{"version":"1.0","type":"rich","title":"Choropleth Map With Interactive Filtering","description":"A choropleth map of world countries colored by economy, with an interactive color legend that filters the map to highlight countries in a selected category. Clicking a legend entry dims non-matching countries and increases their stroke width; clicking again clears the filter. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render topojson country features from the world-atlas dataset, with `d3.scaleOrdinal` and `schemeSpectral` for colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8fa2d5efa5e499991289cbfe42582f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
