Thank you for the great suggestion and link, BOP Mustache. This presentation should serve as a good start.
While reviewing the slides, MMM references a "Prison Sentence Calculator" "straight off of my website" - anyone know where this "HOW LONG YOU HAVE TO WORK" calculator may be found? Presentation standards in my course are such that any graphic must be legible to everyone; its numbers and words are too tiny, but if I could somehow access the original chart settings, I might me able to reduce the number of bars, which would allow me to increase font size or just make the graph easier to decipher due to having less clutter.
