This script retrieves published Azure location information and transforms it into GeoJSON format, with Point features indicating Azure regions and LineString features indicating links between paired regions.

GitHub supports displaying GeoJSON files, but the map rendering is somewhat unstable (sometimes shows only blue, sometimes fixed by force refreshing the page). A better rendering of the same azure-locations-map.geojson can be viewed at geojson.io.
