{"version":"1.0","type":"rich","title":"Fork of Historical Space Launches on a map","description":"This interactive visualization combines a historical space launch map with a brushable time-series histogram. It displays launch sites as red circles on an equal-earth projection, with circle size proportional to launch frequency. A linked date histogram below filters the map by time range. The visualization uses d3.geoEqualEarth, d3.geoPath, and d3.bin for data aggregation, with d3.brushX enabling the interactive selection. Data comes from a CSV file of historical launches and a world atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab22fe659a4546c39b272b5386b5e305?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
