adds an example using PolygonLayer

[naomatheus]

Added a short example notebook using the PolygonLayer together to create a map of municipal boundaries.

TODO: I'll need to add images and/or gifs to make the example more visually appealing.

[naomatheus]

I'd love to add an image or a gif to show the result at the end of the notebook. Any preferred way to do that?
I suppose I would just add an image into the examples directory. Or perhaps a separate directory for the images.
And then link from the notebook with ! [alt_text] path_to_image

Something like that

You can put an image into the assets/ directory. Try to make it relatively small file size. You can do something like brew install imagemagick; convert input.png output.jpg --quality 75. (I forget the exact syntax; that might be wrong)

I'd forgotten that I hadn't given this a full review (feel free to ping me if I haven't reviewed in a day or two), though it would be great to have a screenshot for this as well.

Since it's docs only, this can be merged after the release

[naomatheus]

okay! Moving this out of draft

[naomatheus]

I'm curious how the gif holds up as well
meh the still image looks a lot better

[kylebarron]

This looks pretty good! Just a few comments

[naomatheus]

Hmm... One comment I have here is that I noticed that rendering the entire global map seems to affect the rendering of the fill_color and the map's pickability. When I render the entire map, it is no longer pickable for some reason.

Nice notebook example, Matt. Especially if you can distinguish shape colors by country code. 👍🏽

[kylebarron]

There are some weird artifacts here:

It's hard to know whether that's an issue in the original data or an issue with shapely.boundary or something else. In any case I do also see that the rendering and picking is somewhat slow on my computer. That said, it is 8 million coordinates, so that is quite a lot to visualize!

How about we bring back in the spatial filter over the americas for now? What do you think?

Updated this to use the new PolygonLayer
