Speaking of SVGs, you reminded me of the beautiful SVG documents in David Ellsworth's "Squares in Squares" page [0]. If you view the source of any of them, you'll find the full Mathematica code to generate any constants needed (which is usually simple enough to implement in other CAS software, if you know how to read it), as well as their values listed to dozens of digits within an inline DTD, to be referenced from the actual elements.
