I highly doubt you'll get any good advice on what algorithm you should use for this. I'll bet good money that there are at least half-a-dozen papers in the literature on detecting local dwarf galaxies. You should find those to get an idea of the algorithm, then ask for help about implementing said algorithm.

"Density from a graph" could have so many meanings. Usually a "graph" is something we print on paper, which is why David made is comment about a scanner. Perhaps you meant something else...
