Chord Diagram
String theory

see relationships in data from a whole new perspective

A chord diagram is a graphical method of displaying the inter-relationships between data in a matrix. The data is arranged radially around a circle with the relationships between the points typically drawn as arcs connecting the data together. The format can be aesthetically pleasing, making it a popular choice in the world of data visualization.

Essentially a chord diagram is a pie chart that adds information about relationships.
