{"version":"1.0","type":"rich","title":"Pan and Zoom World Map Cities","description":"This example presents an interactive orthographic world map displaying major cities as points. Users can pan by dragging and zoom with the mouse wheel, manipulating the map’s rotation and scale in real time. The visualization loads country boundaries from the visionscarto-world-atlas TopoJSON and city coordinates and populations from a reduced World Cities CSV. Built with D3’s `geoOrthographic`, `geoPath`, `drag`, and `zoom` APIs, the map renders graticules and updates city positions via the projection each frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89dfd44252d94762bb9b4777450b4ad1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
