Add offline plotting that doesn't depend on Ipython/Jupyter

[nzjrs]

It would be good to have two extra plotly.offline API entry points that return the rendered html for a given plot, and a second that rendered a given plot in a standalone local server.

def plot_html(figure_or_data)
    pass

class PlotServer(object):
    #starts a simple python http server to serve the plotly js / html
    def plot(figure_or_data, return_url=False, open_url=True):
        pass

Silly question:

How can I view the plot (object IPython.core.display.HTML ) without using ipython notebook?

Because when I run a script all I get in the console is:

IPython.core.display.HTML at 0x7f86b38e2a50
IPython.core.display.HTML at 0x7f86b38e2a50
IPython.core.display.HTML at 0x7f86b38e2a50

Ummmm, that's why I filed this issue.

A ok.. I misundersood, thanks! Btw is it possible to sent my output to already running notebook from different terminal?

Great suggestion @nzjrs . I've reserved offline.plot for this functionality, to mimic the py.iplot/py.plot duality.

I think that I'd like to keep this server-less, and just embed all of the JS inside HTML page. That way, it's easier to share stand-alone HTML files (inside of a zipped collection)

[nzjrs]

Sounds good - although I would prefer that function to have an argument that controls the embedding behaviour to be either

• standalone+embedded javascript
• standalone+CDN javascript,
• just the plot javascript+html fragment

[chriddyp]

@nzjrs yeah, that's a great idea. That way, folks can control the size of the bundles that they are sharing.

By default, I think it should be standalone so there are no surprises when they try to open their documents in the absence of an internet connection.

I agree with nzjr with the question I asked here #358 (comment), would be really useful for us.

Hi @chriddyp , plot.ly has been a great tool for displaying interactive 3d data for me, thanks to you and your team! I also would like to chime in and request a standalone offline feature that does not depend on ipython, it would be extremely helpful. I am currently using a hack i grabbed from @pm8k here:

[nzjrs]

The changes are trivial and I will get to making them over Christmas.

However anyone is free to pick up the branch and finish it off. It's really only one hour work, maximum.
