This visualization shows the geographic layout of the ICE-5G glacial isostatic adjustment model, rendering a map of ice sheet thickness and surface deformation. It uses D3’s `d3.geoPath` to draw the land and ice contours, while a color scale encodes elevation and ice thickness data. The code also employs `d3.forceSimulation` for label placement, positioning text annotations without overlap, and accesses raster data via Canvas `getImageData` to sample color values. The rendering approach combines vector shapes with canvas-based pixel manipulation for a detailed, interactive representation of the model’s output.
