Firstly, I just write it for fun, but also focus on high quality real world
applications
since I do not want to use any software design tools that force me dragging
and clicking.

In untyped racket (but may not in the main distribution), there are a lot
of small packages
that focus on one or more subfields of graph visualization and layout
algorithms. In typed
racket, there also are pict3d, plot, and flomap based images. So I think
they definitely benefit
user-designers and covers lots of everyday usage, but user-developers may
need more
extension abilities since modern applications grow too fast.

Therefore, I am writing a modern design engine for programmers with an
elegant functional interface,
graphviz like tool is one of the applications of this engine, actually it
is likely to be the first one.

For now,
* CSS syntax and its computation model is chosen to style elements and
items;
* New architecture and datatypes is coming soon for
reading/composing/writing image resources.

Also I am glad to write the entire tex system in native Typed Racket,
though it is really a huge
project and therefore a long term plan.
