No, this is different. Graphviz is primarily about laying graphs out, and secondarily (if that) about using them to draw diagrams. This is an "open canvas" diagram description language and tool.

The closest I can think of is ditaa (ditaa.sourceforge.net), but ditaa's front end is completely different - it requires you to actually "draw" the picture using text. pikchr (and PIC before it) requires you to describe the picture using words and it will draw it for you.

Plantuml and Websequencediagrams have frontends that are similar, but they are constrained in domain-specific ways. This is any 2D picture (well, within the primitives supported)

Plantuml, IIRC, uses Graphviz in the backend and is in impressive attempt at hiding that fact :). I have spent many a hour trying to get Graphviz to lay a diagram out they way I want it to before learning that the one true way is to let Graphviz be itself - a displayer of the network you described to it, not a displayer of the diagram you want to see.

Pikchr has more in common with svg i think.
