Know your audience
Rafael Irizarry
Graphs can be used for
- our own exploratory data analysis,
- to convey a message to experts, or
- to help tell a story to a general audience.
Make sure that the intended audience understands each element of the plot.
As a simple example, consider that for your own exploration it may be more useful to log-transform data and then plot it. However, for a general audience that is unfamiliar with converting logged values back to the original measurements, using a log-scale for the axis instead of log-transformed values will be much easier to digest.
