ftp/sfdp layout models
Optimized for the following kinds of dot commands:
dot -s72 -Kfdp -Tsvg learning-taxonomy-fdp-2.map > learning-taxonomy-fdp-2.svg
dot -s72 -Ksfdp -Tsvg learning-taxonomy-fdp-2.map > learning-taxonomy-sfdp-3.svg
dot -s72 -Kfdp -Tdot learning-taxonomy-fdp-2.map > learning-taxonomy-fdp.dot
dot -Kneato -Tsvg learning-taxonomy-fdp-2.map > learning-taxonomy-neato-7.svg
Remarks:
* some attributes and even links (edges) needs to be ajusted for different layout models. E.g. sftp works best with a strictly hierarchical graph.
* some attributes are ignored, i.e. sfdp does not look at clusters or pos
* ''pos'' (positions) do not seem to work with sdfp
* A neato model takes a long time to compute (15 minutes or more, others are fast)
