{"version":"1.0","type":"rich","title":"Historical Space Launches on a map","description":"This example shows historical space launch sites as red circles on an equal-earth projection map, with circle size scaled by the number of launches per site. A linked date histogram with a brushed time range filters the map to show only launches within the selected period. The visualization is built with React and D3 v7, using `geoEqualEarth` and `geoPath` for the map, `scaleSqrt` for circle sizing, and `brushX` for the interactive date filter. Data comes from a CSV of historical launches and world atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c83ab7454fae4657afe22cace2684b0f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
