How can I draw an stock chart or a line chart with hundreds points?

I’ve recently written a blog post on creating stock charts in Ext JS 4 – http://www.scottlogic.co.uk/2011/12/ext-js-4-stock-charts/. It uses a couple of hundred points and performs fine in modern browsers and isn’t too bad in IE7-8.
This said however, even after messing with the Ext JS build system, the minimum Ext build required to run the charts is still something like .5MB which is too heavy weight for some applications. The CSS however can be chopped down to just a few rules – if you’re willing to spend the time trying to figure out which ones you need out of the huge ext-all.css!
