[Bug 1289063] Re: dot has no output formats in trusty

[Robert Wall]

Looks like sudo dot -c fixes it. Is this something that needs to be
fixed in graphviz's postinst, then?

dot - graphviz version 2.36.0 (20140111.2315)
There is no layout engine support for "dot"
Perhaps "dot -c" needs to be run (with installer's privileges) to register the plugins?
