A Pie Chart is a type of graph that displays data in a circular graph.In other words, each slice of the pie is relative to the size of that category in the group as a whole. The entire “pie” represents 100 percent of a whole, while the pie “slices” represent portions of the whole.

What are 3 limitations of a pie chart?
Disadvantages
- do not easily reveal exact values.
- Many pie charts may be needed to show changes over time.
- fail to reveal key assumptions, causes, effects, or patterns.
- be easily manipulated to yield false impressions.

What is the difference between column chart and pie chart?
CHART BASICS
Column chart: for comparing data across categories. Pie Chart: for showing the relative shares of categories in a total. Line Chart: for showing trends in a series over time. Scatter Plot: for showing the relationship between two series (given later).
