This visualization shows a choropleth map of earthquake distribution, with the intensity of the data displayed chronologically over the past 7 days. The map is rendered using a WebGL-based framework, likely Three.js, to provide a three-dimensional view of the earth's surface. Each earthquake is represented as a point, with its position mapped using latitude and longitude coordinates from the CSV file. The depth and magnitude of each quake are also visualized, with color and size potentially encoding these attributes. Data is sourced from the USGS earthquake feed, parsed and loaded directly from a local data.csv file using a custom import. The implementation relies on a JavaScript map projection library and a 3D rendering engine to plot the geographic data.
