VIS-AD Data Model: Integrating Metadata and Polymorphic Display with a ScientificProgramming Language

摘要

The VIS-AD data model integrates metadata about the precision of values,including missing data indicators and the way that arrays sample continuous functions, with the data objects of a scientific programming language. The data objects of this data model form a lattice, ordered by the precision with which they approximate mathematical objects. We define a similar lattice of displays and study visualization processes as functions from data lattices to display lattices. Such functions can be applied to visualize data objects of all data types and are thus polymorphic.
