The lack of pimping SVG stems from it being a fifteen year old technology that in terms of web use was first available over a decade ago when the OBJECT tag was introduced.
But nobody remembers that since Adobe buried their IE plugin for it the moment they bought up Macromedia!
Much like X11 you need to put a API on top of it for 'normal' people to use it which is why it was effectively stillborn on the browser a decade ago... the old joke, if X11 didn't suck we wouldn't need Motif, GTK+, QT or any of the other frameworks.
Which is just PART of why there's so much more interest in CANVAS.
Basically SVG is old tech that nobody embraced the first time around -- which is why calling it part of HTML 5 is just so much bull!
But that's also another part of my 'issues' with the HTML 5 specifications -- all these other specs that have NOTHING to do with markup being thrown under it's umbrella for no good reason.
