{"version":"1.0","type":"rich","title":"World Map Visualization","description":"This example displays a choropleth world map where countries are colored by population using a blue sequential color scale. The visualization loads geographic boundaries from Natural Earth GeoJSON and joins them with population data from a CSV file. It leverages D3 v6 APIs including `d3.csv`, `d3.json`, `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.scaleQuantize` with `d3.schemeBlues`. Countries without matching data appear black, while the SVG rendering uses a 800x500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7eec2685acc494c88269fe0c4d4d28f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
