In the previous chapter, we learned about regular expressions, and, in this chapter, we are going to talk all about visualizations. We will be covering the following topics:

• Installing the gnuplot command-line tool and EasyPlot Haskell library
• Plotting our first visualization
• Customizing a visualization to make it publication ready 
• Adding multiple plots to a single visualization
• Learning about the importance of the moving average
• Learning about the importance of feature rescaling
