I found this data viz tool (published in 2015 in the NYT online version) that tracks how the type of jobs that pay middle-class wages has shifted between 1980 to 2012 in the United States (LINK)
This graph uses both lines and colors to convey its information. Lines depict numeric shifts across the 32 year period, while colors (red = blue; women=red) shows the gender breakdown in these numeric shifts.
This graph is both visually striking and ambitious in its attempt to simultaneously convey both numeric shifts (growth versus decline in a specific labor market) and gender breakdowns with respect to each labor market. Admittedly it took me some time to digest just how I was supposed to read the infographic --, particularly what the colors in between blue and red were attempting to convey. But, all in all, a great resource!
