The Daily Island is an island map generated every day. The layers of the map can be hidden and displayed using the controls left of the map.
A previous version generated islands maps as interactive SVG images, using an hexagonal grid.
The current version uses a rectangular grid and the layers are generated as PNG images.
A Mastodon bot, @DailyIsland@botsin.space, publishes the generated map twice a day on the Fediverse.
