Ben Hyde sends along this appealing image by Michael Paukner, which represents a nearly perfect distillation of “infographics”:
Here are some of the comments on the linked page:
Rather than redrawing the picture to make the lines more clear, I’d say: leave the graphic as is, and have a link to a set of statistical graphs that show where the different sorts of old trees are and what they look like. Let’s value the above image for its clean look and its clever Christmas-tree design, and once we have it, take advantage of viewers’ interest in the topic to show them more.
P.S. See my comment below which I think further illuminates the appeal of this particular tree.
