Just a though cairo is wrapped for Lua and can render to svg
Its a clean easy to use C api with the graphics functions working
a bit like a logo turtle
Could make of an easy to implement low level part of what you
are trying for...

The idea is that Lua syntax is a bit nicer to craft than XML, but

allows programmatic creation of macro-like objects (functions that
create
graphical objects) that can be turned around, copied etc.. SVG has
a "uses"
element for that, but this is more easy on the eyes (clearer code).

There's a number of ways to design this [1,2], and some ways can be
expressed in terms of wrappers around other ways. I've been tending
to settle on Asko's style, which avoids the function and environment
(which has undesirable qualities like locals outside the function
overriding environment variables and environments complicating static
methods of detecting undefined variables [3]). As Asko mentioned,
the
Lua structure is somewhat like XML, and in that way it can be made to
work like pure data provided you don't intersperse other Lua
constructs into it (which unfortunately complicates clean round-trip
serialization).
