It took me a sec too. It's a confusing application, since the intent is to compare to adjacent rows.. the first one for example is "half furloughed" but only a slightly smaller red line. Visually confusing.
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.
