Title: circular presentation graphs

I've take the original Listeners and Publishers from the EVENTS.md and applied style=invis to retain the circular presentation.
Also changes the arrow direction for the Publishers.
But I have not made any corrections to the data nodes, I thought it best to leave that to you.
take a look below, and if you like then merge my EVENTS.md
