yFiles Ajax: Web Diagram Tool

Category: Dojo, JavaScript, Library

<>p>David Alberts of yWorks GmbH has created yFiles AJAX, a library for creating web based diagrams built on top of the Dojo Toolkit.

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.

Launch Demo

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.

Launch Demo

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!

There seems to be more pluses than minuses with the nodes.
