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.

For the chart, see Pie chart.
For other diagrams, see Circle diagram, Smith chart, and Nyquist plot.
