Benefits & pitfalls to avoid
- Pie charts are often criticised. Comparing the size of pie segments can be difficult, and many visualisation experts suggest that bar-charts should be used instead.
Create your own
- There are currently no commercial applications that create cartograms, although some routines are available on the web from Cartogram Central and World Mapper.
- Pie charts can be created in a range of standard data applications such as Excel.
