{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays world countries colored by income group, with a legend that filters the map when clicked. Selecting a category dims non-matching countries and highlights the selected group, while the legend also remains interactive. Built with d3.geoPath and d3.geoNaturalEarth1 projection, it loads geographic data from the world-atlas TopoJSON dataset and supports zooming via d3.zoom. The color legend renders SVG circles and text with click handlers, using d3.scaleOrdinal with the color schemeSpectral. Hovering over a country turns it red, and tooltips show the country name and income value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff32329d94544d17b2e3611fc0fcccc7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
