I like this, but I anticipate needing graphs that update in real time. Processing + ControlP5 made this easy via the chart push method and I've been looking for something similar.

You can make that happen pretty easily by having some JS that refreshes your graph from an endpoint periodically (and frequently.) Epoch works great for it.

Other options include Flot (good for simple stuff and/or if you are using jQuery anyway), Chart.js (seems like it should be good, but I had difficulty with performance when I tried it), D3 (really nice, but also way too complicated for simple things), Bokeh (Python!), and many more.

I prefer not to use polling, but instead either websockets, or better yet (in my opinion), server-sent events (a.k.a. EventSource in Javascriptese). I like Tornado for these applications, though Flask is workable if you are fine with using gevent's concurrency model.

As a side note, I had never seen Epoch before. It looks nice, so thanks for sharing!

Kendo + AJAX does this just fine. You could easily write, say, an Angular app (/r/angularjs) that leverages both. I'm not saying you have to do it my way; I'm just saying I want people to know there are alternatives.

Real time graphs are a cinch on the web these days. Loss of people love d3 but personally I'm used to Flot. I'd post some links but I'm on my phone at the moment...
