Mountains on a Map
A world map displays space missions as circles, with radius encoding the number of missions per city and color representing the country, overlaid on a Natural Earth projection. Using d3.geoPath for land, graticules, and sphere rendering, the visualization employs d3.scaleSqrt for circle sizing and React for component structure. The data comes from a CSV of space mission coordinates, with country boundaries from World Atlas TopoJSON, styled with muted fills and opacity for overlapping points.
