Circle Graph Data Interpretation

The video tutorial explains how to interpret circle graphs, also known as pie charts. It covers the concept of part-to-whole relationships, where each section of the circle represents a percentage of the total 100%. The tutorial includes examples of circle graphs displaying favorite sports and desserts, and demonstrates how to calculate specific data points using percentage proportions.
