{"version":"1.0","type":"rich","title":"GeoVisualization - Choropleth map of the world","description":"This example presents a choropleth map of the world, coloring each country according to its population using a threshold color scale with sequential blues. The visualization uses D3.js (v6) to load GeoJSON and CSV data, projecting the map with a Mercator projection via `d3.geoMercator` and drawing paths with `d3.geoPath`. Interactivity highlights countries on mouseover by adjusting opacity and stroke, while the SVG rendering displays the result.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e094443ba50941a9ab10cbeda9c1f774?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
