How to draw a line graph using ggplot with R programming. Plots and graphs to visualize data.

The video tutorial covers creating graphics using ggplot, a package within the Tidyverse in R. It explains the types of variables, such as categorical and numeric, and how to plot them using Cartesian planes. The tutorial introduces built-in datasets in R, focusing on the Orange dataset, and demonstrates various data visualization methods, including bar charts, histograms, box plots, and density plots. It provides a detailed guide on using ggplot to create graphics, emphasizing data mapping, aesthetics, and geometry.
