Explore / Integrate regional "Demographics" population maps per country

[skipjack]

So this would be a new visualization with "Demographics" and only on the country-specific pages. It would set us up for a third-level of "Explore" depth (right now we have "Worldwide" => "[Country]").

We'll need two types of data to bring this to life...

• GeoJSON for regions within each country to draw choropleth map (@skipjack - looks like this might help).
  • https://en.wikipedia.org/wiki/ISO_3166-2:US
  • https://www.volkerkrause.eu/2021/02/13/osm-country-subdivision-boundary-polygons.html
  • https://geojson.io
  • https://developers.google.com/maps/documentation/javascript
  • https://plotly.com/python/mapbox-county-choropleth/
• Historical regional population data for each country (@JeydenP).

Countries to focus on:

• USA
• Great Britain
• Canada

Sources we're seeing for US Population data...

• https://worldpopulationreview.com/states

• https://www.unfpa.org/data/world-population/US

• https://data.census.gov/table?q=Population+Total&g=040XX00US36&y=2011

• https://wisevoter.com/state-rankings/states-by-population/#florida

• https://www2.census.gov/programs-surveys/popest/datasets/

And regarding country subdivisions more broadly...

• https://en.wikipedia.org/wiki/ISO_3166-2

Sources that can be used for UK(Great Britain) population data...

• https://populationdata.org.uk/english-counties-by-population-and-area/
• https://wikishire.co.uk/wiki/Counties_of_the_United_Kingdom

To start, since it looks like we'll need to do this on a per-country basis, we can use the enrichCountry methods in the [country_code]/index.js modules. So for the US that would be src/us/index.js. We'll break that up into multiple functions after you have it working and submit the PR.

To store the data, for now something like this should work...

country.attributes.statistics[year].populationBySubdivision = {
  'US-NY': 2392302,
  // ...
}

@JeydenP here's that package we were discussing...

• https://www.npmjs.com/package/iso-3166-2
• https://github.com/olahol/iso-3166-2.js

Looks like that iso3166.subdivision("US", "Indiana") call would be the easiest based on our conversation.
