The Visualizer requires a replay file to run. Replay files are generated when the gameserver is done executing a game with a minimum of two players.
You can even drag & drop a replay file into this page to rewatch an older replay!
All Infos about what CORE GAME is & how to participate can be found here and the source code can be found here.
