{"version":"1.0","type":"rich","title":"(interactive) Choropleth Map","description":"This interactive choropleth map visualizes global economic data across countries using a spectral color scale. The map supports zooming and panning via d3.zoom, with a clickable color legend that highlights matching countries and dims others. Built with d3-geoPath and a Mercator projection, it renders SVG paths from TopoJSON data sourced from the world-atlas dataset. The legend uses d3.scaleOrdinal and d3.schemeSpectral to map categorical values to colors, with opacity transitions indicating selection state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0fb27164e12a4396805b8cee92af6093?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
