A pie chart (or a circle chart) is a graphical representation of data that looks like a circle is divided into sectors each of which represents a proportion of the whole.
You can use Google Docs to design pie charts for free. Google Spreadsheets can be an easy and free graph maker for you allowing you to create a pie chart, a 3D pie chart, a donut chart as well as design your pie charts on iPad:

When to Use Pie Charts for Data Visualization?
Pie charts work great for clearly visualizing percentages and proportional data. They don’t work well for complicated data or large sets of data.
As a rule, it is better to use pie charts when you have no more than 6 categories / sections. More categories will make the pie chart to crowded and hard to understand.
Unlike a bar graph (or a bar graph), pie charts are not able to show changes over time, so they can only be used to visualize the current state of things.
Pie charts work well for illustrating how one category clearly compares to another category.
Overall, charts and graphs are great online research tools that demonstrate numeric data obtained from a survey.
It is best to use contrasting colors to visualize chart sections to make it easier for an eye to clearly see the relative contribution that different categories contribute to the overall total.
Pie charts can be used to visualize:
- Monthly expenses
- Breakdown of votes
- Customer / user preferences (favorite choices)
- Website traffic sources, etc.
To create a nice pie chart, you don’t need any design skills. Google Spreadsheets can be your free and easy chart maker, so it’s probably the easiest way to create data numeric visualizations.
