How to customize the HTML / use in GEOlayers

Change the web map code: docs/HTML.md - explains index.html, GeoJSON paths, layer order, colors.

After Effects GEOlayers: docs/GEOLAYERS.md

  1. Download GeoJSON above after removing the region.
  2. For HTML: point the three data: paths at your new .geojson files (see HTML.md).
  3. For GEOlayers: Browser -> Import File -> draw country-minus-region as highlight.

Data: Natural Earth countries + geoBoundaries (ADM1/ADM2). For Russia, ADM1 also includes disputed regions from Natural Earth (e.g. Crimea).
