Learning R for Data Visualization (Video 14)

This video tutorial explores how to change the default color scale in GGPlot2, starting with altering the two default colors and then increasing the number of colors. It highlights the importance of color scales in data visualization, showing how different scales can reveal trends and anomalies in data. The tutorial provides practical instructions for implementing these changes in R Studio, using functions like scale_color_gradient and scale_color_gradientn to achieve smooth transitions and enhanced data interpretation.
