[Moose-dev] Efficient Roassal Layout

Hi, I have a collection of objects (revisions of a Git repository) and I'm trying to build a tree of all the revisions (about 14k). I already computed the neighboring relationships, thus for each revision I know parents and children revisions. I wrote a small Roassal script to build a tree and I tried with subsets of revisions (i.e., 50, 100, 200, 300). Everything works fine until I reach 375 revisions or so.. After more than 10 minutes the graph was not yet displayed. So, I profiled the execution and discovered that the bottleneck is the ROHorizontalDominanceTreeLayout I'm using. I know that the Dominance Tree Layout is expensive to compute, and I was wondering if you could suggest a layout to display a tree with more that 300 nodes. Thanks in advance, Roberto
