Jinwook Seo and Ben Shneiderman,     University of Maryland, College Park

The Hierarchical Clustering Explorer provides a dendrogram and color mosaic linked to two-dimensional scattergrams, a variety of visualization options, and dynamic query controls for use in genomic microarray data analysis.

Molecular biologists and geneticists seek to understand the function of genes, including the more than 6,000 genes in the yeast genome and the estimated 40,000 genes in the human genome. Recently developed for genome analysis, DNA microarrays—also known as gene arrays or gene chips—usually consist of glass or nylon substrates that measure 1 × 3 inches or smaller. These chips contain specific ...
