dot-str takes options to let user specify shape of nodes, size of graph, etc.

I would like to specify the shape of nodes (square vs round, for instance), the size of the graph, etc. Is this possible? If not, could it be added?

Currently, it's not possible to do this in Loom, but I think graphviz does have this ability, which just needs to be enabled by passing the params through https://github.com/aysylu/loom/blob/master/src/loom/io.clj#L34. If you'd like to add this, that'd be great!
