{"version":"1.0","type":"rich","title":"world map","description":"This example shows a choropleth world map colored by each country's economy classification, with a clickable color legend that filters and highlights matching countries while dimming others. The map uses d3.geoNaturalEarth1 and d3.geoPath to render TopoJSON world-atlas data, with d3.zoom enabling pan and zoom interactions. A d3.scaleOrdinal maps the spectral color scheme to the economy categories, and tooltips display country names and values. The SVG rendering includes CSS hover effects and opacity transitions for non-selected regions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/785475916b40491697c9641ab03aaaab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
