Create User Interface to Display Data in (Editable) Flowchart Format

Scope of Project: Problem: There is no visual aid for User to see the link/path to all the nodes and which one is linked together, thus removing a node can disrupt other path's and/or entire system. Objective: To create a user interface (any programming language is okay - preferably Microsoft tools) that will allow the User to visualize the existing data from the database in flowchart format to create node path(s) and visually see where node(s) lie or connected to other nodes and be able to make modifications to path and/or node. We seek an agent scripting /visual interface similar to a flow chart style. User Interface can be browser or console application.
