In this video, I'm going to walk you through the process of creating a visualization with ggplot, and then in the next chapter, we'll explore different types of visualizations. The ggplot function is the core function that we use to create visualizations. By itself, the ggplot function simply creates an empty plot. But then we can use the grammar of graphics to add different elements onto that plot, including geometries, aesthetics, mappings, and scales.
