The visualization maps meteorite landings across the globe, encoding each fall's mass (g) through mark size and layering class type and chronological order over geographic position. It uses D3's `geoPath` for the base map and applies a sequential color scale to distinguish meteorite classifications, while a time-based slider filters year ranges. The dataset from NASA's Meteoritical Society is loaded via ESM imports, with numeric parsing of mass and coordinates handled in the data preprocessing phase.
