Artistic World Map 2
The visualization renders a world map where landmasses and ice sheets are filled with flowing, rainbow-like colors derived from a maze generated using Prim’s algorithm. A flood-fill process colors each maze cell, and the result is clipped to the land and ice boundaries using a Canvas 2D context with `d3.geoPath` and `topojson`. The map uses a Mercator projection and modifies the color of each pixel via Canvas `getImageData` and `fillRect`. Country boundaries come from the world-atlas TopoJSON dataset.

This map uses Prim's algorithm; however, I have used the implementation of this algorithm found in Mike Bostock's blocks. I've essentially only modified it to change the fill colors. This is another attempt to create an artistic world map, see also this block.
