Claim:
A data visualization system comprising: an interaction database maintained in a computer memory of interaction data representing interactions between customers and at least one merchant; a retrieval component configured to retrieve from the interaction database data representing interactions between customers and the merchant, and to construct a finite set of data values from the retrieved data; a display component configured to display a graphical representation of a merchant and a graphical representation of each of the set of data values centered on respective data points disposed on a representation of a sphere; and a contour generator configured to generate and display one or more contour lines at least partly around each data point to form a raised surface, in which each data point is displayed as a local maximum at the center of the raised surface, and value of the local maximum is dependent on at least the angle between a first notional line connecting the center of the sphere and the data point and a second notional line connecting the center of the sphere and a co-ordinate of one contour line.
