{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a world map rendered as gray countries with white borders, overlaid with white circles marking populated places from Natural Earth data. Hovering over a country or city highlights it in pink or blue, respectively. The visualization uses D3 v3's `d3.geoMercator` projection and `d3.geoPath` to draw GeoJSON features from two remote sources: world-110m.geojson for countries and ne_50m_populated_places_simple.geojson for places. Circles are positioned via the projection’s coordinates and respond to mouseover and mouseout events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fa3cdd1209c4fb481b8814b266feb57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
