Register entry point for pandas backend

[TomAugspurger]

pdvega could add an entrypoint to register itself with pandas: https://dev.pandas.io/development/extending.html#plotting-backends

Something like

# in setup.py
setup(  # noqa: F821
    ...,
    entry_points={
        "pandas_plotting_backends": [
            "altair = pdvega.<module>",
        ],
    },
)

where <module> is whatever module has the plot top-level method with the right signature.

My plan on this is to deprecate pdvega and create a new altair_pandas package that will implement the pandas API and register an altair entrypoint. Much of pdvega was written in vega directly rather than in Altair.

Good to know. Do you have a rough timeline on that transition? The pandas 1.0 release will be sometime in October. It'd be nice if pandas' document had some rich examples using the various plotting backends. That doesn't have to be tied to the 1.0 release, but we may get a bit of extra attention since it's 1.0.

Good to know. I'd like to tackle it soon, but I don't have as much time for these things as I used to 😄

Understood only too well :)
