About the Daily Island
The Daily Island is an island map generated every day. The layers of the map can be hidden and displayed using the controls displayed on the page, left of the map.
The 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.
