yFiles Ajax: Web Diagram Tool
Category: Dojo, JavaScript
, Library
A couple of demos are available such as:
Graph Viewer
The Graph Viewer Demo Application
demonstrates viewing a graph with zooming,
panning, overview and additional node and edge information.Realizing a slightly simpler version of this application is described step by step
as a tutorial in the
Developer’s Guide.
Collapsible Tree
Initially, a rooted tree with many nodes is loaded into the canvas. However, most
of the nodes are not shown, because their subtrees are collapsed. The nodes are
rendered with custom icons that indicate their current state. You can collapse or
expand nodes. After an expand or collapse operation, the graph is redrawn using a
configurable layout algorithm.Realizing a slightly simpler version of this application is described step by step
as a tutorial in the
Developer’s Guide.
Graph Editor
With the
Graph Editor demo application you can add new nodes
and edges to a graph, move or delete nodes, change node labels, apply a
layout algorithm, download the current graph etc.. For details see the online help
of the application.

It’s too bad this is an Ajax based diagram tool. The numerous hits to the server really impact the user experience.
JGraph went with a different approach in mxGraph and only hit the server on initial loading and saving. The user doesn’t have to wait for a response from the server when manipulating nodes and interacting with the diagram.
I suppose there are pluses and minuses to both approaches.
Congrats on the accomplishment though, I can’t wait to see where it goes!
The demos doesn’t work very well. Very disappointing!
I’m pretty excited about ZIMBRA’s approach, and have a feeling that a lot of RIA is going to go this way. It only makes sense, in fact, and I wonder why we never thought of it sooner.
ZIMBRA is not the only one, right now, employing this kind of model and I am eager to see how this race ends- or, at least where the next begins.
There seems to be more pluses than minuses with the nodes.
I think I’ll be preoccupied this weekend. These are great demos. More likely, I won’t be asking for more.
