问题
there was an application called 'WorkflowMonitor' that was included with the samples kit for workflow 3 which gave you a visual playback through previously run workflows.
The tracking records that app works against appear to be a different shape to those in workflow 4, is there a similar viewer that anyone knows of that can give me an insight into previously run workflows in workflow 4?
I am really just looking for the best way to interpret the data, the Workflow Monitor would have been perfect, but appears to be incompatible now.
Thanks,
Dave.

I know near to nothing about WF3 but, based on your request, you might want to start by downloading this WCF/WF Examples package.
Take a look at WF\Application\VisualWorkflowTracking solution to see a visual tracking system in action.
See also the concept of Workflow Tracking Participants on WF4, on these links:
- Workflow Tracking and Tracing
- Tracking Participants in .NET 4 Beta 1
A small introduction from the first link:
Windows Workflow tracking is a .NET Framework version 4 feature designed to provide visibility into workflow execution. It provides a tracking infrastructure to track the execution of a workflow instance. The WF tracking infrastructure transparently instruments a workflow to emit records reflecting key events during the execution. This functionality is available by default for any .NET Framework 4 workflow.
The examples package contains a bunch of example code about tracking on WF_WCF_Samples\WF\Basic\Tracking folder.

@Jota's answer is a good one, you should look at those examples. The visual tracking example is kind of a mess though. A few of us of done some different variations that separate the running of the workflow from the viewing of the tracking data.

and my own version with signalR but based on the visual tracking sample http://panmanphil.wordpress.com/2012/11/05/slides-and-sample-from-the-chippewa-valley-code-camp/
Looks like you have some reading on your hands.
