visualize the GnuPG web of trust -

is there way visualise gnupg web of trust? (or other) key in middle, signed keys in first circle, trustpersons' trustpersons in next , on?

if there nothing that, should able build based on key signatures lokal keyring, right?

one approach convert output of gpg --list-sigs dot file can rendered graph graphviz tools.

use gpg, sig2dot, , dot this:

gpg --list-sigs | sig2dot.pl > gpg.dot dot -tps gpg.dot > gpg.ps evince gpg.ps
