Let’s initialize a basic ggplot based on the midwest dataset. The second noticeable feature is that you can keep enhancing the plot by adding more layers (and themes) to an existing plot created using the ggplot() function. All the data needed to make the plot is typically be contained within the dataframe supplied to the ggplot() itself or can be supplied to respective geoms. The main difference is that, unlike base graphics, ggplot works with dataframes and not individual vectors. The syntax for constructing ggplots could be puzzling if you are a beginner or work primarily with base graphics.

This tutorial is primarily geared towards those having some basic knowledge of the R programming language and want to make complex and nice looking charts with R ggplot2. This is part 1 of a three part tutorial on ggplot2, an aesthetically pleasing (and very popular) graphics framework in R.
So, for practical purposes I hope this tutorial serves well as a bookmark reference that will be useful for your day-to-day plotmaking. It goes into the principles, steps and nuances of making the plots effective and more visually appealing. I start from scratch and discuss how to construct and customize almost any ggplot.
