In this tutorial, we’ll cover the key concepts of pie charts, along with a realistic example, and use Visual Paradigm Online to visualize the data. Key Concepts of Pie Charts Definition: A pie chart is a circular statistical graphic divided into slices to illustrate numerical proportions. Each slice represents a category’s contribution to the total. Data Representation: The size of each slice is proportional to the quantity it represents. The whole pie represents 100% of the data. Use Cases: Displaying market share of different companies Showing survey results Visualizing budget allocations Limitations: Hard to compare similar-sized slices Not effective for large datasets Can mislead if not properly labeled Realistic Example: Market Share of Smartphone Brands Let’s consider the market share of different smartphone brands in a given year: Brand A: 30% Brand B: 25% Br
