When Firefox knows that your exported HTML file is really XHTML
(thanks to you changing `org-export-html-extension' to "xhtml"), you
can embed SVG into it. For example, here are PIC diagrams:
http://home.avvanta.com/~sand/org-mode/embedded-pic.xhtml
Those are the first two diagrams in "Making Pictures With GNU PIC"
(http://www.kohala.com/start/troff/gpic.raymond.ps).
It should be possible to do something similar for the "dot" exporter.

So ... are you going to implement this, asking for an implementation,
or what...?

Still experimenting. I got Dot working last night. The problem is
we're missing some layers of abstraction:
* If I submit code that lets "pic" blocks generate SVG for HTML,
then things won't work properly for people without SVG-capable
browsers. We need some way for a user to say "When exporting
HTML, render PIC using SVG".
* The current "dot" and "ditaa" control mechanisms work by exposing
command-line arguments, which get sent to the underlying program.
Bernt Hansen's document example uses
#+begin_dot gv01.png -Kdot -Tpng
The "-Tpng" directive and the ".png" suffix should be implied by
an "I want PNG" configuration, and the "-Kdot" should be implicit
in the directive name. There's definitely a need to allow
command-line args on a block-by-block basis, but they need to be
qualified by the rendering mechanism at least.
* There are other arguments that you want to send to Emacs to do
post-processing on the external program's output. I use those to
shrink the PIC SVG output down to something more manageable.
In my examples, they are the "7in 1in" arguments; they are only
meaningful for PIC-in-SVG, as the "pic2graph" tool always uses an
8in x 8in canvas.
Taking all of this into account, we might come up with something like
the following:
#+begin_export pic html:svg latex:eps docbook:svg ascii:nroff
#+render_args eps :filename "figure_3_1.ps"
#+render_args svg :width "7in" :height "1in" :command "-F Times"
ellipse "document";
arrow;
box "\fIgpic\fP(1)";
arrow;
box width 1.2 "\fIgtbl\fP(1) or \fIgeqn\fP(1)" "(optional)" dashed;
arrow;
box "\fIgtroff\fP(1)";
arrow;
ellipse "PostScript"
#+end_export
The new directive is "#+begin_export". First argument "pic" defines
how to interpret the contents. The remaining arguments are supported
publishing types and what renderer to use. Those are all optional;
users can set up their own defaults.
The "#+render_args" directive indicates a renderer, with a
property-list following. My inclination is to have something that
Emacs can suck into a plist. By convention, the ":command" tag
contains the arguments to pass down to the child process.
Comments?
