System for creation of visual representation of data

摘要

A system for displaying related data in a graphical representation is disclosed. The system allows display of data visually to demonstrate requested data and data which is related to the requested data. The requested data is sent from a data source to a client computer via a programming object which has a display manager which creates display entities for the formatting of graphics on a display screen. The display entities have properties which define the appearance of the entity on the display screen. The programming object also has a position manager routine which creates position entities for the placement of the entities in a global space. The position entities have properties which define the location of the entities in the global space. The programming object also has a graph manager routine which creates graph entities for selection of data records from the data source. The graph entities have properties which determine the selection of data records. The programming object also has a source manager routine which creates source entities which have properties to represent the data records. The system includes an authoring program which allows a user to create the programming object via various editors which allow creation of the four managers to obtain different representations from the data source.
