{"version":"1.0","type":"rich","title":"D3 trials (fork of Cities on a Globe)","description":"This interactive globe displays cities with populations over 100,000 as red circles, using an orthographic projection with drag-to-rotate and zoom capabilities. The visualization renders country boundaries from TopoJSON world-atlas data (110m resolution while dragging, 50m when stationary) and city locations from a CSV file, with circle sizes scaled by population. Tooltips show city names and populations via d3-tip. The implementation uses d3.geoOrthographic, d3.geoPath, d3.drag, and d3.zoom, filtering out cities on the hidden hemisphere based on their projected coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8c95cf58caa45b69faad42d0a6b7009?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
