Oh, I think using Python to create the JS, and then embedding that directly into the website is fine! Once I get the plot styling correct, I don't anticipate having to change it much, so I can hard-code it in the site. Is that best done via bokeh.embed.file_html()?

HI Alex,
First just a note about the figure(...) function. It was changed in 0.7 to return a Figure (plot) object. So if it is returning None that indicates yo are using an older version of Bokeh.
Next, regarding using BokehJS directly, unfortunately the early BokehJS "plotting" interface was broken in 0.7 due to some other changes. It was never really intended to be a permanent fixture, it was really just something created in a hurry early on to be able to test some things out, as devs. However, there is not (yet) anything to replace it. Here is the GH issue you can follow regarding a real BokehJS interface:
https://github.com/bokeh/bokeh/issues/1515
If you have thoughts on what a good JS interface would look like or how things might be spelled, please adder input on that issue!
In the mean time there are a few options:
* Use python to create the JS, then throw the python code away (bokeh.embed functions can emit the JS you want)
* Use BokehJS > 0.7 directly, right now this would mean doing everything "by hand" and would be somewhat tedious
* Use the Bokeh.plotting functions with BokehJS < 0.7.0 (an example: http://jsfiddle.net/bokeh/Tw5Sm/light/\)
I very much hope that all or most of the issue for new BokehJS interface will be ready for Bokeh 0.8, tentatively scheduled for mid to late February.
Thanks,
Bryan

Right now it is possible, but a little bit of a pain, to feed data to a Bokeh plot directly from JS, or to update it in the notebook without using the server. It will probably be a few weeks before all the other pieces and are in place and these new examples are ready, but I will make sure to announce them to the mailing list when they are.
