This is definitely one of the fancier graphs I've done using ggplot2. Made it for a report for a client agency.
I got to use multiple lines, points, error bars, and facets. I learned tricks for rotating, resizing, zooming, etc.
None of that compared to the days of data munging this required, so... ddplyr for the win. Thanks, Hadley Wickham!
I'm feeling accomplished.
