In this primer, we will build on these foundational skills (from the R fundamentals course) and use the ggplot2 to create seven data graphics: histogram, density plot, bar chart, line graph, scatter plot, area chart, and a boxplot. In addition to plotting the charts, we will refine the charts to ensure they apply the design standards as described in Data Visualization Made Simple: Insights into Becoming Visual. The data is from Capital Bikeshare.
