Describe the argument structure contained in the parent document and mark-up the appropriate statements using microdata. The microdata should be parsed from the parent and used to construct the JSON graph description for the vizualiser.

Barricade should take a json document describing the argument structure as an argument. This should be parsed and used to construct the visualisation

Default behaviour on Firefox is for the graph to settle and become fixed at which point you can no longer select the nodes or move them. This behaviour only occurs on Chromium the very first time you launch the widget in a freshly launched browser. If the page is refreshed this behaviour does not re-occur. Afterwards you can drag and move nodes as required.

This is probably a bug in the underlying arbor library code as the same behaviour occurs with the default sample project included in the arbor archive.

The browsers checked are:

• Chromium 14.0.835.202 (Dev. Build 103287 Linux) Ubuntu 10.10
• Firefox 8.0

It would be nice if Barricade could be used with older browsers from the pre-canvas days. NB. Look at how jqPlot have used excanvas to provide support for IE browsers that don't natively support the HTML5 canvas element.

The modal popup should display data associated with the visualised argument. When a node is mouse-overed the popup should display the meta-data for that node.

The json description should be accessed from a remote location
