Encircled observations - use ggplot and ggalt to create great plots and data visualization.

The video tutorial explains how to encircle a subset of data in a plot using the Star Wars dataset. It introduces the Tiny Verse library and GG Plot for data visualization, focusing on the GG Alt add-on and its encircle function. The tutorial guides viewers through setting up the environment, creating a new object for human characters, and using the encircle function to highlight specific data points. The video concludes with finalizing the plot and encouraging viewers to explore further resources.
