"Best practices" way to access a plot from Javascript

I was just curious about the "best practices" way to look up a plot from Javascript.

I am currently using bokeh.embed.components to produce Javascript and divs that I include in a static HTML document. In particular, I am not using a server, so I tend to write some Javascript to update ColumnsDataSources and whatnot. I know that it is possible to use CustomJS for this purpose, but I prefer to just write the Javascript directly as I do a lot of non-Bokeh things along with the Bokeh updates. This is all pretty straight forward once I get my hands on the plots in questions, but its not entirely clear to me how I should be doing that.

Currently, I do something along the lines of:

doc = Bokeh.documents[0];
fig = doc.get_model_by_name("my_fig_name");

Is this the right way to go? Is Bokeh.documents an implementation detail, or should I consider that part of the public API? Is there some other function that I should use to get my hands on the Bokeh document object from Javascript?

Thanks,
Gerard

maybe you could submit a code example of your approach (you can skip all the data and unrelated stuff; I’m just interested in the embedding code)? We have some work going on improving bokeh’s templating capabilities, so this may be useful to cover more cases with this work.
