Forum: Rails Spinoffs (closed, excessive spam) building/editing topology diagrams - any ideas/advice?

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/....
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

When I started teaching myself Prototype and Scriptaculous I wanted to
write a Visio-type of program.

The idea was to be able to add draggable boxes to the workarea and to
be able to connect lines between them and to be able to add text and
attibutes to the boxes.

I never finished it, but you're welcome to take a look at/steal the
code. It kind of works. The hardest part was the automatic line
routing.

thanks James, will do.

I guess you didn't find an existing open source project that had
already implemented such an app or library?

PS.  Does Prototype and Scriptaculous not cater for drawing shapes?
Is this why you had to use Water Zorn's SVG library then?
