{"version":"1.0","type":"rich","title":"Fork of Historical Space Launches on a map","description":"This interactive visualization combines an equal-Earth projected world map with a brushed time-series histogram to explore historical space launches. Circles sized by launch frequency mark geographic sites, while a linked date histogram with a brush filter controls which launches appear on the map. The example uses React with d3-geo’s `geoEqualEarth` and `geoPath` for map rendering, d3-scale’s `scaleSqrt` for circle sizing, and d3-brush’s `brushX` for filtering. World topology comes from the World Atlas TopoJSON dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/87d5d08d6d8d42e8a9139a999fc5d66f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
