This is a cool experiment

Though it'd discourage anyone to run off with this idea.. b/c SVGs are unfortunately kinda janky

My top 3 issues are:

- not even overly complicated SVGs, especially with text, will render notably different in different browsers (and renderers like Batik/Inkscape/SalamanderSVG/etc). I have no idea why.. PDFs don't have this issue. While I haven't tried, but I don't think PDFs are as easy to generate programmatically as SVGs

- SVGs have completely broken linking. You can embed an <svg> inside another <svg> to reuse an element - but for some reason it's limited to a link depth of 1! So you can't link an <svg> that links an <svg>. So SVG aren't safely composable - which drives me nuts.. (ex: making a large display panel in SVG that has subcharts)

- Maybe minor.. but tooltips in SVG (which are super handy.. for instance in plots to display additional info about a data point) don't work when the SVG is in an HTML page. They seem to only work when you open SVG in a separate tab.

More abstractly they just have very weird perf issues. Some mildly complex SVGs take GBs of RAM and 1> min to render. But it's unclear which parts are performance sinks.
