@heydon @jorbefore SVG was widely used, I was experimenting w/ how to integrate it w/ PHP, tending to prefer avoiding javascript if possible. This website is garbage to look at, but the SVG title is dynamically generated by PHP. simple silly thing, but i thought it was cool at the time! It took a lot of detailed editing to get it to work "right" -- at least without throwing errors:
