A Quick and Dirty Guide to Exploratory Data Visualization

One of the things I've noticed teaching statistical fundamentals or working with colleagues is the lack of focus on first visually exploring the data.  Novices seem to want to jump right in with correlations and statistical tests without getting a...

Vary many aspects of geom_segments in ggplot, and see what emerges. The things...
