The GenoViz project provides tools for genomics data visualization. It consists of the following: 1) the GenoViz SDK, a library of re-usable components, 2) the Genometry data model to represent relationships between biological sequences, and 3) the Integrated Genome Browser (IGB, "igbee"), an application built upon the GenoViz SDK and Genometry for visualization and exploration of genomes and corresponding annotations from multiple data sources. IGB supports the Distributed Annotation System (DAS) protocol, version 1 and 2, as well as other optimized binary data formats that are designed for efficient exploration of large, whole genome data sets.
