This application helps visualise the variable categories for each axis of the XAI4BCI design space.
A chord diagram is a graphical method of displaying the relationships between data in a matrix. It is used to visualize the connections or relationships between a finite set of entities. The entities are represented as circular segments, and the connections between them are illustrated using ribbons or chords. The entities are represented as circles around the perimeter of the diagram, each circle corresponds to an individual entity. The chords are the arcs connecting pairs of entities. The width of the chord may be used to represent the strength or frequency of the relationship between the connected entities. The input is a matrix, where the rows and columns correspond to the entities, and the matrix entries represent the strength or frequency of the relationships between them. The color represents the different entities around the disk. The colors are chosen arbitrarily.
