- maps
- icons
- gauges
- dials
- histograms
- pie charts
For the full list visit the Epic. Graph blog. If you can think of any other commonplace visualizations then please suggest them to Mark (the Epic. Graph blogger). I've suggested the financial indicators used in business news (TV, print, web) to indicate daily movements in stocks, indices, exchange rates, commodity prices etc.
