building/editing topology diagrams - any ideas/advice?

[Anonymous user]

Hi,

I'd like to build a web application that is capable of displaying & editing topology diagram (e.g. a network diagram with applications
too). Effectively to have a graphically web based means of allowing a user to add nodes & relationships to represent a topology such as the following [http://performancepointinsider.com/files/planning/planningtopology.png|http://performancepointinsider.com/files/planning/planningtopology.png] .
So the model basically consists of nodes and relationships.

Any ideas/advice on how best to do this, e.g.:
Q1. Any open-source project that does something similar?
Q2. Best way of handling the graphical aspect of the application?
(e.g. prototype, extjs, etc?)

Thanks

calagga,

Kivio is an opensource alternative to Visio. Not sure if this is an applicable solution for you, but it's the closest fit I know of.
