## What is a circle graph simple definition?

In graph theory, a circle graph is the intersection graph of a set of chords of a circle. That is, it is an undirected graph whose vertices can be associated with chords of a circle such that two vertices are adjacent if and only if the corresponding chords cross each other.

## What will we do in interpreting the data presented in a circle graph?

Circle graphs – Graphing Data When interpreting the graphs, we are asked to determine the number of people represented by given percentages in our graphs.

What is a circle graph called?

A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented.

What are the circle graphs called?

pie chart
A pie chart (or a circle chart) is a circular statistical graphic, which is divided into slices to illustrate numerical proportion.

### Why do we use circle graphs?

A circle graph, or a pie chart, is used to visualize information and data. A circle graph is usually used to easily show the results of an investigation in a proportional manner. The arcs of a circle graph are proportional to how many percent of population gave a certain answer.

### What are circle graphs best used for?

What are circle graphs used for?

A circle graph, also commonly referred to as a pie chart (sound familiar?) is a simple and visually appealing chart divided into wedges, each of which represents a data value. It’s one of the most commonly used graphs for displaying statistics, so we certainly can’t take its popularity for granted.

What percentage does a whole circle graph represent?

A circle graph shows how the parts of something relate to the whole. A circle graph is divided into sectors, where each sector represents a particular category. The entire circle is 1 whole or 100%, and a sector of the circle is a part.

## How many sectors are in the circle graph?

A circle graph is divided into sectors, where each sector represents a particular category. The entire circle is 1 whole or 100%, and a sector of the circle is a part. Let’s define the various regions of a circle graph.

## When should circle graphs be used?

What is the meaning of a circle graph?

Circle graphs, also called pie graphs or pie charts, quickly show, in a very easy to understand fashion, what proportion of the whole is represented by each type of category listed. As you can imagine, this makes for a very useful graph.

How to draw circle graph with central angles?

Now, simply draw a circle and draw radii off from each side of your central angles to represent each group, and you’ll have your circle graph. This gives you a powerful visual representation that quickly shows people that most of your customers are in the 18-25 and 25-34 age range.

### How many percentage points are in a circle?

After all, there are 360 degrees in a circle, but a data set typically has only 100 percentage points. In this lesson, we’ll look at not only how to use circle graphs but how central angles help us to draw more accurate graphs.

### Is the donut graph the same as a circle graph?

Donut Chart Functionally the same as a circle graph, but with a hole in the center, this type of graph is able to support multiple statistics as one. Exploded Donut Chart This chart is the same as a donut chart, but the wedges have ‘exploded out,’ much like the Exploded Circle Graph.
