nice work! doing quick graphs is very easy when you use paper and pen, but it's always been a pain to do with a computer!

I assume this tries to be simple enough, but maybe it would be nice if we could have some extra, quick formatting, like dashes, like in lists (-) to stack elements, or other symbols for different layouts, quick access to colors, etc. I know handling multiple layouts and auto-placement with springs simulation can be tricky, but hey... in any case, thanks again for the work, hopefully it inspires more people to work along these lines!
