Chord with large number of nodes Part of PowerCharts XT
Chord diagram is a visually appealing way to represent weighted relationships in a radial layout. Entities (or categories) among which the weighted relationship exist are drawn on the circumference whereas the actual weighted relationship are drawn as links in the circular space of the chord diagram. The essence of a chord diagram is in knowing the dominant relationship and one can toggle to narrow focus on most important relationships.
Chord diagrams can be used particularly in large sporting events where they have to establish the upper-hand in different fixtures as shown below.
