Add choropleth maps for metropolitan and non-metropolitan areas (MSA's)

[mbkupfer]

Any chance we can add an ability to create choropleth maps of United States Metro and non-Metro Areas. I feel that this could be done since there is already a county map and metro are simply supersets of counties. Here is the definition of metro areas provided by the BLS. https://www.bls.gov/oes/current/area_definitions_m2017.xlsx The Excel sheet download can be used to map counties to metro and non-metro areas.

Here is an example of this used in practice

Found this shape file that could be used: http://brenocon.com/geocode/cbsa.tiger2013.json.gz

Will follow up later with my initial findings.

@jonmmease, follow up: I inspected the shape file and good news! The GEOID is a perfect match to the AREA column in the definitions file above. The CBSA file is (almost) a superset of the area definitions w/over double the amount of areas. That said, there are some areas, 50 to be exact that are in the definitions, that aren't covered in the CBSA. I did a set difference and provided them below. These all seem to be metro divisions though which leads me to believe that their constituent metro areas will already be included.

As for coding this figure factory, I'm happy to give it a shot. I haven't used geopandas before, but it's coming pretty natural as I'm commonly using pandas. I also have _county_choropleth.py to work off of. Going to create a similar version called plotly/figure_factory/_core_based_statistical_areas.py. Will keep you posted.

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
