This is a great illustration of "An infinite number of mathematicians walk into a bar. The first goes up to the bartender and says, "I'll have a pint of lager, please." Each next one says, "and I'll have half of what he's having." The bartender says, "You're all idiots," and pulls two pints."

Is there a way to export SVG to PostScript from within a browser, or otherwise extract the SVG at a given rendering state? It would be a great way to make publication-quality figures while having something interactive to document in a web-based journal.

Yes, but it's mesmerizing to do so.
Thanks, gen, that go-chips-chips-all-the-way-down doodle was just what I needed to clear my head this morning.

I don't know how this is an illustration of that, Space Coyote, but that's my new favorite joke.

Just looking at how the circles get so much smaller as they split into parts, it just reminded me of that pattern.

So good. Thanks, gen.
What strikes me about several of the HTML/CSS/JS demoes I've seen in the last few months is how joyful they make me feel. In many of them, user interaction combines with visual aesthetics in a surprising and wonderful way.
LOVE THIS STUFF.

Mike Bostock is also the software designer behind Protovis and Polymaps, two other amazing Javascript libraries. D3 is his new thing. It's one part jQuery, one part Protovis. I'm still wrapping my ahead around it, it's a fairly small but dense library, like a Webern cantata. But all the better for it.
I just ported a visualization over from Protovis to D3 and enjoyed the experience. D3 lets you easily go in and directly build graphs with SVG, it's very document oriented as opposed to the more procedural style of Protovis. One neat thing is you pop open Firebug or Chrome Dev Tools and there's your graph right there, in the DOM, and you can easily debug and tweak it. And the graphics look great; SVG is a real hidden gem.
One thing D3 enables is transitions. You see it in the koalas in the animation of how the circles split. The stacked bars demo is nice too, click the buttons Group/Stack for the transitions.

version="1.1" xmlns="http://www.w3.org/2000/svg"to the svg tag before the browsers would render it.

:( The D3 examples don't work for my newest, off the shelf/reference-quality IE instance, which sucks as I would have loved to use some of these in a forthcoming project, especially if I could count on it cross-platform...

It seems that Internet Explorer doesn't support SVG without a plugin, and as far as I can tell D3.js only uses SVG.
You might look into Raphael.js, which supports IE by using VML for IE and SVG for other browsers. It's pretty easy to use, but it's a lower-level drawing library, so you'd have to build your own charts. Or you can try gRaphael, a graphing library built on Raphael.js. I haven't tried gRaphael, but here's an example from the New York Times.

I'm impressed it took 7 hours before someone noted that these don't work in IE. Not so many IE users on Metafilter, maybe? IE8 and older does not support SVG, and the koalas page doesn't even detect the lack of feature :-( IE9 offers SVG support but I haven't heard anything yet about how well it might work. Anyone try these examples in IE9?
D3 itself does not require SVG; it happily manipulates any DOM. The treemap example is divs. But if you want to draw graphics with DOM, SVG is your practical option.

I was doing the same research on this earlier today, looks like IE 9 has been in beta for a year but is close to Release Candidate.

IE9 has been in release candidate for about a month, and is scheduled for official release at a blowout at South by Southwest on St. Pat's day. Because nothing complements getting drunk and pretending you're Irish like a desktop web browser. Apparently.

You can pull the SVG out of the DOM, yes, but not in the state that it is in after making interactive changes to it (see the widgets in the second link).
