ViViaN(TM) (Visualizing VistA and Namespace) is an OSEHRA developed, web based
tool for viewing and browsing relationships among hierarchical and connected entities.
Originally developed to allow browsing of the VistA code base via a tree-based
functional decomposition of the code, ViViaN has expanded to include
tree-based visualizations of VistA menus and the VHA Business Function Framework
categorization; as well as circle plots of the interaction network among VistA packages.
This circle plot captures the interrelationships among VistA packages.
