Here's a nice tutorial from Nathan Yau's Flowing Data blog using R and US state-level crime data. It shows:
- Box-and-Whisker Plots (which you already use)
- Histograms
- Kernel Density Plots
- Rug Plots
- Violin Plots
- Bean Plots (a weird combo of a box plot, density plot, with a rug in the middle).
Lately, I find myself plotting CDFs much more than histograms.
