update `plot_spatial_weights` for new libpysal api

[knaaptime]

when the libpysal change goes live (libpysal.weights.W(...use_index=True) it will break the spatial weights plotting function

[martinfleis]

We wanted to refactor that anyway and merge the plotting method we have here with the one over in lib anyway. So it may actually be a candidate for a quick-ish PR.

[knaaptime]

while we're at it, one thing it would be nice to add is auto ability to scale linewidths by weight value for nonbinary weights

[knaaptime]

also maybe an interactive analogue

[martinfleis]

An easy way to do those would be to create a GeoSeries from the links and use geopandas plot and explore methods but it means one more copy of the data as an intermediate step.

[knaaptime]

thats what i had in mind. And maybe @walkerke would be willing to contribute his interactive LISA code?

[martinfleis]

I thought that's just explore over LISA labels, no?

[knaaptime]

yeah pretty much. just a function to wrap the labels and hit explore

[walkerke]

Looking through splot I think an interactive analogue to the methods that wraps .explore() would be pretty useful. Happy to take a look at it.
