There is no data that can be displayed in a pie chart, that cannot be displayed BETTER in some other type of chart.

The greatest value of a picture is when it forces us to notice what we never expected to see.

To be able to say that "if we change our point of view in the following way ... things are simpler" is always a gain.

This is my favorite part about analytics: Taking boring flat data and bringing it to life through visualization.

Numerical quantities focus on expected values, graphical summaries on unexpected values.

I know of no person or group that is taking nearly adequate advantage of the graphical potentialities of the computer.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
