Key Concepts

Pie Chart

A pie chart is a circular graph divided into sectors, with each sector representing a proportion of the whole. It is used to illustrate numerical proportions and is particularly effective when you want to show parts of a whole and compare their relative sizes.

Categorical Data

Categorical data refers to values that can be placed into groups, or categories. Each slice of a pie chart represents a different category, making it easy to visualize the distribution of data according to these groups.

Percentage and Proportions

Percentages and proportions are key in constructing a pie chart because each sector's size is determined by its percentage share of the total. These metrics enable a viewer to understand how large one category is in relation to the entire dataset.

Data Visualization

Data visualization is the practice of representing data graphically to communicate information clearly and efficiently. Creating charts such as pie charts helps in summarizing large datasets into understandable and easily interpretable visuals.
