bjjmap is a free, interactive 3D knowledge graph of Brazilian Jiu-Jitsu (BJJ). Explore every position — closed guard, half guard, mount, side control, back control, turtle, standing and more — as nodes in a constellation you can orbit, with the moves, sweeps, submissions, escapes and transitions that connect them drawn as paths between the positions. It is a map of the whole ground game, for beginners finding their way and advanced grapplers charting new lines, built and corrected by the people who train it.
