Title: Radiation Dose Chart

These two displays contrast empty (informationless) infographics with high-content ones (perhaps too high for a static display).
The one at the left is a parody of a newspaper textbox labeled "By the Numbers," similar to this image, where the goal is only to attract the reader's attention. That's OK. Just don't try to present it as a pie chart, or pretend that it is an Infographic.
The one at the right, Randall Munroe's xkcd webcomic site attempts to show something serious in an infographic - the levels of an ionizing radiation dose a person can absorb from various sources, and put them in perspective over many scales, with descriptions of what a given value means.
The unit in the chart is the "sievert" (Sv), the effect a dose of radiation will have on a human body. The chart spans many orders of magnitude, from Sleeping next to someone (0.05 μSv), to a chest x-ray (20 μSv), to a fatal dose, even wih treatment (8 Sv), and finally to the dose from 10 minutes next to the Chernobyl reactor after meltdown (50 Sv).
