Libellula depressa, commonly known as the broad-bodied chaser or broad-bodied darter, is a dragonfly in the family Libellulidae. One of the most common dragonflies in Europe and central Asia, its range extends to England, central Asia and the Middle East, with a few limited populations in Scotland. It is not found in Ireland or North Africa, however. This insect is around 39 to 48 millimetres (1.5 to 1.9 inches) in length, with both the male and the female having a broad, flattened abdomen which is brown with yellow patches down the sides. In the male, the abdomen develops a blue pruinescence that covers the brown colour. Both fore and hind wings have a dark patch at the base. This male L. depressa dragonfly was photographed at Wolvercote Lakes in Oxfordshire, England.

Graphs edit

I love it how Aboriginal paintings depict a whole story.

Good graphs can also tell a story, as Edward Tufte describes in his books on data visualization.

Global warming edit

Daily Sea Surface Temperatures 60S-60N 1979-2023

This Copernicus graph is a jewel. It is a graph that tells a whole story in an instant.

The blue, white, red lines are like waves of an ocean. The colours seem to show increasing temperature, yet actually show time, decades of data. Time and temperature coincide.

2023 jumps out of the waves, is out of bandwidth. Oceans are warming.
