CGView
CGView (Circular Genome Viewer) is a freely available downloadable Java software program, applet and API ( application programming interface) for generating colorful, zoomable, hyperlinked, richly annotated images of circular genomes such as bacterial chromosomes, mitochondrial DNA and plasmids. It is commonly used in bacterial sequence annotation pipelines to generate visual output suitable for the web. It has also been used in a variety of popular web servers (the CGView webserver, PlasMapper, BASys) and databases ( BacMap).
