Project Management Histograms, Earned Value, and Quality Charts

Search the Internet for a project resource histogram (example attached to this prompt), value chart (example attached to this prompt), and at least two different quality control charts (examples attached to this prompt). Write a 700-word paper describing each chart found on the Internet, what it shows, and how it can assist in managing a project (for project management). Include a screenshot of each chart that is found on the Internet, along with a reference in APA formatting (Be sure the references are cited with author, date, title, as well as URL).
(The four photos attached are just a sample as to what you should be looking for on the Internet. These four photos do not belong in the essay and do not count as research.)
