What is ggplot2?

• ggplot2 is a data visualization package for R
• developed by Hadley Wickham
• inspired by Leland Wilkinson's "The Grammar of Graphics"

Why ggplot2?

• ggplot2 provides an organizing philosophy for building graphs – a structured approach to graphing
• “The emphasis in ggplot2 is reducing the amount of thinking time by making it easier to go from the plot in your brain to the plot on the page.” (Wickham, 2012)
