Bar Charts & Pie Charts

During this learning journey, I have developed a clear understanding of key concepts and skills for data visualization:

1. Comparisons vs. Compositions

• Differentiated between visualizing comparisons (showing differences between categories) and visualizing compositions (showing parts of a whole).

• Learned to identify appropriate chart types for these two types of analysis.

2. Bar Charts

• Created and customized bar charts for comparing categorical data using geom_col(), geom_errorbar(), and position adjustments.

3. Pie Charts

• Designed and customized pie charts to visualize compositions using coord_polar() with geom_col().

These skills have enhanced my ability to present data effectively for comparison and composition analysis using {ggplot2}.
