content: Most of the information here contains huge caveats that are never described: geographic specificity, types of businesses included, types of "engineers" included, and their education level.  Based on some reasonable assumptions given the presentation, I would say this information only represents SF Bay area, startup companies seeking computer programmers with a BS-degree.  Somewhat informative (though, very poorly designed graphics choice of line orientation over a grid background) if you fall into or are interested in that specific category, however, completely misrepresentative of all engineers, all education-levels, all types of companies, and all areas.
