Interactive graph visualizer in NIPSYS64 (font + palette graph)

I ve been working on a special mode that helps visualize various graph structures used by my engine. For testing, I ve chosen the autogenerated weighted graphs of font characters and palette colors linked according to similarity (computed as the rootmeansquare error). Such graphs should be useful when converting images into pseudographic text resembling ANSI art. These fonts use my extended character set named SGC, and also my 256color shell palette. Some heuristic is used to keep the link number for every graph node reasonably small. The graph is interactive and animated using numerical approach to solve dynamics; links produce attract forces and all nodes repel each other with exponential falloff. Some further optimizations can be done to enhance performance for larger graphs. See project s IndieDB pages for more cool stuff:
