{"version":"1.0","type":"rich","title":"Cheap tricks for interactive maps","description":"This example demonstrates interactive zoom and pan on a world map rendered with SVG. It uses the Natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath to draw country boundaries and a blue sphere background. The map loads GeoJSON data from the world-atlas TopoJSON file on CDN, with country names supplied by the data’s properties. Hovering changes country fill color via CSS, while d3.zoom applies event-driven transforms to the map group. The visualization relies on D3 v5 and TopoJSON client libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/04bd153a9f3f4fd88084aa8a102f5e48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
