If you are interested in modeling systems and sharing those models you are in the right place.
We use GraphVix, Neo4j's Arrows Tool, SVGs, Omnigraffle, OPCloud.
Graphviz is fully integrated into the platform.
Almost any model that can be rendered in SVG format can be imported into a FedWiki.
All interactive objects (more than pictures) in our models and graphs can create an associated page with a single click.
We can make sense of FedWiki content with automatically generated graphs (network diagrams).
