Is it possible to import bokeh figures from the html file they have been saved in?
As of Bokeh 1.0.2, there is not any existing API for this, and I don't think there is any simple technique that could accomplish this either. I think the only options are: some kind of (probably somewhat fragile) text scraping of the HTML files, or distributing all the HTML files and using something like <iframe> to collect the individual subplot files into one larger view. 
Going forward, for reference there is autoload_static that allows plots to be encapsulated in "sidecar" JS files that can be individually distributed and embedded, or there is json_item that produces and isolated JSON representation of the document that can also be individually distributed and embedded.
I've produced a few Bokeh output files as the result of a fairly time intensive process. It would be really cool to pull the plots together from their respective files and build a new output file where i could visualize them all in a column. I know I should have thought to do this earlier on before producing all the individual plots, but, alas, i did not. 
Is there a way to import the preexisting figures so that I can aggregate them together into new multi-multi plot output file?
