In brief, our product includes a web-based process flow component, typical nodes-and-edges kind of thing. Much better done with SVG IMHO, with first-class support for box & line modelling and styling. But the powers-that-be decreed we'd do it all in HTML & CSS.
Well, I'll happily agree that SVG is a perfect fit for data-driven graphics, but that represents are reasonably large set of solutions, so I'd not say "useless" at all.
