This visualization uses earthquake data from a USGS dataset to map seismic events by location and magnitude on a world map. Each earthquake is represented as a circle, with its size scaled by magnitude and its position determined by latitude/longitude coordinates. The depth of the quakes is encoded through color, creating a gradient from shallow to deep events. The map is rendered with SVG paths for continents, and a custom tooltip provides details on click or hover. Circles are drawn with D3's data-join and scaled using a linear magnitude scale, while the map projection and graticule are set up with D3's geo utilities. The visualization highlights the global distribution and intensity of recent seismic activity, with Nepal, Japan, and the South Pacific clearly standing out.
