Abstract

We introduce a descriptive model that allows the definition of a large class of information visualization algorithms with a small number of parameters. Compact visualizations, which we conjecture is equivalent to the class of visualizations that can be rendered in a time directly proportional to the size of the input data, are defined by a fixed dataflow architecture: clustering and subclustering of input data, sort, graphic primitives and graphic attributes generation. At each step, the parameters are expressions of the host programming language, which include input attribute names and local variable names. Local variables are a specific concept that allows us to extend the expressiveness of the dataflow architecture. We introduce our model formally, and then show its expressiveness with a few examples.
