This visualization presents the locations and characteristics of meteorite landings on a world map. Using D3.js with the `geoNaturalEarth1` projection and `geoPath`, it renders landings as scaled circles based on mass. The map uses the D3 `scaleSqrt` for radius and color-codes points by meteorite class. An interactive legend filters visible points by broad category and subcategory. Geographic data is fetched from a TopoJSON world atlas via `topojson-client`; landing data comes from a CSV file.
