This stacked, grouped bar chart is a mess! There isn't much right about it: the colors are blinding, the group labels are taxing, the grouping is obscure, the scale should have been in millions, and neither axes have labels.
Stacked bars, sometimes used in place of pie charts, are not much of an improvement. For example, it is difficult to read from this chart the operating expenses for the medical school because it is at not the bottom of the stack.
By simplifying, the junkart version manages to gain clarity. The colors are not necessary but I include them to provide reference to the original chart. Apparently, the author saw it fit to cluster the departments into three groups, namely the 4 largest faculties (blue), all other academic departments (green), and non-academic departments (orange). On this chart, one can easily see that the Medical School spent close to $500 million in 2004.
