Warranty data visualisation system and method

A method of data visualisation comprising the steps of:

• maintaining in an interaction database interaction data representing interactions between customers and merchants involving one or more items;
• retrieving from the interaction database data representing interactions between customers and merchants;
• constructing a finite set of data values from the retrieved data;
• displaying a graphical representation of at least one item;
• and
• superimposing one or more contoured representations of the data values on the graphical representation of the item such that each data value is displayed as a local maximum.

A data visualisation computer program comprising:

• an interaction database of interaction data maintained in a memory, the interaction data representing interactions between customers and merchants involving one or more items;
• a retrieval component configured to retrieve from the interaction database data representing interactions between customers and merchants and to construct a finite set of data values from the retrieved data;
• and
• a display component configured to display a graphical representation of at least one item, and to superimpose one or more contoured representations of the data values on the graphical representation of the item, such that each data value is displayed as a local maximum.
