I know that Web Workers don't have access to the DOM, but I was wondering if there was any way they could render a Sparkline graph behind the scenes and pass it back. If not, is there ANY way I could use Web Workers to speed up the processing of around a million sparklines?

I'm trying to improve performance (see this question)

如果你看这篇文章：http ://hacks.mozilla.org/2009/07/working-smarter-not-harder/你可以传回要绘制的点（x，y坐标），然后当你发布接收端只需要处理它（绘制它）的消息。

因此，如果您分析将成为瓶颈的部分的应用程序，您的性能影响将出现在每个图形的渲染中。

为什么要在客户端渲染它们呢？试试 Google Chart API http://code.google.com/apis/chart/docs/gallery/line_charts.html。
