R Programming for Statistics and Data Science - Building a Bar Chart with ggplot2

The video tutorial covers creating bar charts using ggplot with Titanic data, focusing on categorical variables. It explains the differences between bar charts and histograms, and demonstrates how to use aesthetic mappings to enhance graph clarity. The tutorial also explores faceting graphs by class and gender to analyze survival rates. The lesson concludes with a summary and a preview of the next topic, which involves two-variable plotting with box and whisker plots.
