Visualizing Average Rainfall in the US by State
The inspiration for this post came to me while randomly browsing data sets on the internet. I found this page and decided to practice using ggplot2 to make heat maps. First, I had to transfer the data from the table on the website into a .csv file in Excel so I could properly import the data into R.
The code itself is very short which shows just how powerful and efficient ggplot2 really is.

I love that ggplot2 includes a legend for the graph by default.
