A user-written command for Stata called coefplot was released by Ben Jann recently. It is a very accessible program which can create nice graphs very easily. It is particularly good at working with margins output and seems superior to marginsplot based on my experience with it so far. A particularly nice feature is the ability to combine estimates from several different regressions (example below). The paper is full of examples of the kind of graphs the command can produce and is worth reading.
