13. The computer according to claim 12 , wherein if an additional entity of a particular entity type is stored in the storing step, the location on the graph of the allocated entities is adapted in accordance with the additional entity.
12. A computer for providing a visualization graph, the computer comprising: a storage medium having recorded therein processor readable code processable to provide a visualization graph; a database for storing data corresponding to a plurality of entities having a particular type, wherein a semantic net includes the entities and wherein the entities are linked to each other by a plurality of relations; a query interface adapted, so that in response to a query with respect to an entity selected from the plurality of entities, a visualization graph is provided representing the results of the query, wherein the code comprises an allocator code processable to: allocate a first of the entities, representing results of the query, displayed because it is a focus entity defined by the user or the query; allocate a second of the entities, representing the results of the query, displayed because it is directly related to the focus entity, wherein a third of the entities, representing the results of the query, is not displayed because it is indirectly related to the focus entity; allocate a fourth of the entities, representing the results of the query, that is indirectly related to the focus entity, wherein context information is used to determine that the fourth entity be displayed; allocate a first set of the entities to a predetermined sector of the graph depending on an entity type, the predetermined sectors being subdivisions of a screen area with boundaries; allocate a second set of the entities to a predetermined sub-sector being a subdivision inside the boundaries of the predetermined sector depending on an entity sub-type, the sub-sectors also having boundaries, wherein a size of the predetermined sub-sector depends on a number of the second set of entities allocated to the predetermined sub-sector, wherein the predetermined sector has a size that depends on a number of the first set of the entities allocated to the predetermined sector and the number of the second set of the entities allocated to the predetermined sub-sector; and provide an invisible attractor in the predetermined sector, which attracts a subset of the entities to the predetermined sector depending on the entity type of the subset of entities, wherein the invisible attractor remains invisible during user interaction with the visualization graph.
