startType
has the syntax (style)?(seed)?.
If style is present, it must be one of the strings "regular", "self",
or "random". In the first case, the nodes are placed regularly about a
circle. In the second case, an abbreviated version of neato is run to obtain
the initial layout. In the last case, the nodes are placed randomly in a unit
square.
If seed is present, it specifies a seed for the random number generator. If seed is a positive number, this is used as the seed. If it is anything else, the current time, and possibly the process id, is used to pick a seed, thereby making the choice more random. In this case, the seed value is stored in the graph.
If the value is just "random", a time-based seed is chosen.
Note that input positions, specified by a node’s pos attribute, are
only used when the style is "random".
