Ah, that chart on the bottom is on a log scale. I wasn't expecting that... and if I didn't look closer I would have completely misinterpreted it (for example, it appears that the DoD is mostly shut down).
The author really should consider this and think hard about what point he is trying to make with that chart on the bottom.
To try to avoid the confusion, I'm working on another graph of percentages working for each agency, and a disclaimer about the scaling.

NASA, HUD, ED are the most affected, not DOD.
Edit: took another look, and it is quite a bit more confusing than I thought, because of furloughed vs total employees. I can't quickly tell if the furloughed for an agency is linear based on the percentage of the total employees for that agency, or is also logarithmic.
