This visualization combines a world map with a time-series histogram to explore historical space launches. The map displays launch sites as proportional circles, using a square-root scale for circle radius, while the histogram shows launch frequency by month and includes a brush for filtering the map by date range. Built with D3 v7 and React, it uses `geoEqualEarth`, `geoPath`, and `geoGraticule` for map rendering, `bin` and `brushX` for histogram binning and interactive filtering, and loads land topology from a world-atlas TopoJSON source.
