Pie chart?

A pie chart is a circular statistical graphic that is divided into slices to illustrate numerical proportions. Each slice represents a proportion of the whole, with the size of the slice corresponding to the percentage it represents. Pie charts are commonly used to show the distribution of data and are useful for comparing different categories or showing the relationship between parts and the whole.

What is a pie chart?

A pie chart is a graphical representation of data, in which the data is divided into different sectors, each representing a portion of the whole. The size of each sector is proportional to the size of the corresponding data value.

How to create a pie chart

To create a pie chart, you will need to:

1. Collect your data.
2. Calculate the percentage of each data value.
3. Draw a circle.
4. Divide the circle into sectors, with the size of each sector proportional to the percentage of the corresponding data value.
5. Label each sector with the corresponding data value.

Each type of chart has its own advantages and disadvantages, so it is important to choose the right chart for the data you are trying to visualize.
