Introduction to ggplot2

ggplot2 is a visualization package in R. It was developed in 2005 and it uses the concept of the Grammar of Graphics to build a plot in layers and scales. This is the syntax used for the different components (aesthetics) of a geometric object. It also involves the grammatical rules for creating a visualization.

ggplot2 has grown in popularity over the years. It's a very powerful package, and its impressive scope has been enabled by the underlying grammar, which gives the user a very file level of control - making it perfect for a range of scenarios. Another great feature of ggplot 2 is that it is programmatic; hence, its visuals are reproducible. The ggplot2 package is open source, and its use is rapidly growing across various industries. Its visuals are flexible, professional, and can be created very quickly.
