Abstract: The biological pathway graph is a visual representation of pathways.Although there are many biological databases which provide visual analysis tools for pathways,a web-based tool for visualizing and editing biological pathway is yet available.This paper develops a web-based visualization and editing tool for biological pathways and introduces its key design technologies and system structure.This system is developed to assist researchers browsing and retrieving information,to help them understand biological processes and explore the relationship among the pathways.
