Since your svg file is sort of minimalistic, and all the ongoing drawing is done by script, a 'canvas' solution probably wouldn't do worse? Well, I'd probably expect that canvas vector drawing will present some kind of lowest denominator for simple browser based graphing (eg. map directions, stock charts, ...)? Still unpleasant, but at least no plugin penalty. Make sure you check http://me.eae.net/stuff/iecanvas/demo.html. In fairness I should mention A. Quint's (only related) earlier work as well (http://fuchsia-design.com/CanvaSVG/). Hooray, it’s snowing;-)

Anyway, the above script definitely works in It's a shame too, because I had been using getAttributeNS(null, "cy", ...) without a problem but I thought I'd try to optimize by using baseVal. I'll have to revert that change for asv 3.03... That is really odd, since I thought I tested in asv 3.03 as well as asv 6 tp1… maybe what I thought was asv 3.03 was really asv 6 tp1?

It's dirty work to write svg scripts that smells good to asv and ff at the same time:-(( Eg. in asv createElementNS(SVGNS, "circle") will create an 'Element'. You can't expect a circle cy attribute from an Element. You can not access attributes in asv like 'this.elem.cy.baseVal.value=..' (this.elem.setAttributeNS(null, "cy", ..)), etcpp... Jeff,

I had sped it up to watch the snow accumulate, but in my next iteration I'll slow it down again. It’s just a constant.
