The Hilbert path is a single contiguous line that can fill a volume without crossing itself. As a data structure, Hilbert paths are useful because ordering along the curve preserves locality: points -that close together along the curve are also close together in space. +that are close together along the curve are also close together in space. The converse is often, but not always, true. The coloration reflects this.
