This visualization displays historical space launch sites as red bubbles on an equal-earth projection map, with bubble size encoding the number of launches at each site. A time-series histogram beneath the map shows the monthly launch count, with a brushable selection that filters the map’s bubbles to the chosen date range. The code uses D3 v7’s `geoEqualEarth`, `geoPath`, `geoGraticule`, `scaleSqrt`, `bin`, and `brushX` APIs, rendered as SVG within a React framework. Geographic data comes from the world-atlas TopoJSON file, while launch records are loaded from a CSV file.
