cl-svg
cl-svg offers a somewhat friendlier way to produce SVG image files than hand-rolling XML.

CL-SVG doesn't attempt to cover all the nooks and crannies of SVG, but the library should be usable for most needs. The source comes with the file testing.lisp which has many examples you can experiment with via SLIME.
