Visualizing data

Visualizing data is one of the best ways to carry out graphical EDA. Visualizing data with plots and charts allows us to discover facts about the data that may not be very obvious when applying quantitative EDA techniques:

• ggplot2: One of the best packages to visualize data in R is ggplot2. It is so popular with the R community that it has almost become an industry standard.
• GGally: This is another package that helps visualize data created in a data frame. It includes various plot features such as creating matrix scattered plots.
• Scatterplot3d: This package helps create 3D scatter plots, which adds more visualization features.
