A circle with five chords and the corresponding circle graph. In graph theory, a circle graph is the intersection graph of a chord diagram.That is, it is an undirected graph whose vertices can be associated with a finite system of chords of a circle such that two vertices are adjacent if and only if the corresponding chords cross each other.
They are easy to combine with other visual variables to represent additional attributes, such as colors and pie charts. However, disadvantages of circles have also been raised, especially that circles are aesthetically uninteresting, and that psychophysical studies have suggested that people are worse at judging the relative areas of circles ...

A chart (sometimes known as a graph) is a graphical representation for data visualization, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". [1] A chart can represent tabular numeric data, functions or some kinds of quality structure and provides different info.
