it is a circle graph
In graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In other words, it can be drawn in such a way that no edges cross each other.
Select any value for one of the variables in the graph and solve the equation to get the other variable.
A chord
Circumference (perimeter) of a circle = pi x diameter Diameter of a circle is the straight line distance from one side to the other which passes through the centre of the circle.
The other name for the line of symmetry of a circle is the diameter. The diameter of a circle is a line segment that passes through the center of the circle and has endpoints on the circle itself. It divides the circle into two equal halves, making it a line of symmetry. This means that if you were to fold the circle along the diameter, both halves would perfectly overlap.
Circle Chart or Circle Graph
It's a Pie graph or Pie Chart are two other common names for a circle graph.
In a circle graph it is easier to see shares of the total than in other kinds of graphs.
It's a circle that kind of looks like a pizza cut into pieces. Usually, the pieces are labeled as something (usually you compare things with a circle graph) and normally have percents along with the label. I'm sorry, I explained it the best way I could.

To learn more about a circle graph; Also known as pie graph, check this out!http://www.fedstats.gov/kids/mapstats/sconcepts_pie.html < Copy and paste into your broswerThis shows you how a pie/circle graph looks and also tells you what its used for.A quick copy and paste from the site if your too lazy to do all of that."A circle graph or pie graph is used to show how a part of something relates to the whole.This kind of graph is needed to show percentages effectively."(The example is on site! go check it out if your still confused)>In graph theory, a circle graph is a graph whose vertices can be associated with chords of a circle such that two vertices are adjacent if and only if the corresponding chords in the circle intersect. In other words, a circle graph is the intersection graph of a set of chords of a circle.
a bar graph
This could be called a "Circle Graph" or a "Pie Chart". They are most commonly used for displaying percentages and other statistics.
Do you mean a Pie chart? It looks mostly like a circle. Specifically, a circle whose interior is divided into parts: a right angle to represent a quarter of the whole, a 60-degree angle for 1/6, a 45-degree angle for 1/8, and other such sectors for similar divisions.

A bar graph is a graph that has vertical or horizontal bars to represent numbers. A bar graph is usually used to compare two different things with each other.
A circle graph (also called pie chart, because the different data representations look like slices of a pie) will represent the data as a portion (percentage) of the whole (a full circle). A bar graph will show absolute values of each data. Both graphs allow you to compare the different data categories to each other (which one is biggest, smallest, etc.)
it is more easier to see which subject has more than the other
