{"version":"1.0","type":"rich","title":"Choropleth map interactive filtering","description":"This example presents a choropleth map of the world, where countries are colored according to their economy using a spectral color scale. The map supports interactive filtering: hovering highlights a country, and clicking a legend item dims all countries except those matching the selected economy category. The visualization is rendered as SVG using d3.geoPath with a geoNaturalEarth1 projection, while the color legend is built with d3.scaleOrdinal and d3.schemeSpectral. Country data comes from the world-atlas TopoJSON dataset, merged with TSV metadata. The zoom and pan interaction is enabled through d3.zoom, applying event.transform to the map group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96df44ebb34e48848a9329e391b6cb20?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
