Circle of Life
The genome of Gloeobacter violaceus, drawn as a gorgeous circular plot by visionary biological data artist Martin Krzywinski (from this paper). Within its concentric layers of information are buried genome composition, relation to other species, and overall genetic structure. It’s also very pretty.
Gloeobacter is an ancient photosynthetic bacterium that branched off the rest of the photosynthetic tree (including cyanobacteria and, later, plants) and has its own strange way of eating sunlight.
