Charting and ranking apocalyptic events

For Domain of Science, Dominic Walliman attempts to chart all of the deadly events that threaten humanity on a scatterplot. On the horizontal axis he places number of casualties. On the vertical he places likelihood. So something like, oh, say, a global pandemic ends up in the top middle of the plot.
