One way to improve your ggplot visualizations is by leveraging themes. Themes provide a consistent and professional appearance to your plots by adjusting elements such as grid lines, axis labels, and backgrounds. By choosing a theme that aligns with your visualization’s purpose, you can make your plots more visually appealing and easier to interpret. Using themes with you plots can give them a more professional look.
Themes are added to a plot by adding the theme at the end of your plot code. p + theme_minimal(). If there other custom theme elements that you want to add you should do that after calling the theme function.
