{"version":"1.0","type":"rich","title":"Circles on a map","description":"This visualization shows a world map colored by each country's economy category, with a legend displaying the color scale on the left side. The map uses a natural Earth projection, rendered as SVG paths with a blue ordinal color scheme. The code loads geographic data from world-atlas TopoJSON and country metadata from a TSV file, merging them via ISO country codes. Interaction includes zooming via d3.zoom and a hover effect that turns countries red. The color legend is built with custom d3 selections, circles, and text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/095722cecef745858206d1092af4baff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
