I have been tasked with displaying a Workflow. We have our own custom Workflow engine (don't ask) which defines the different workflows, steps and transitions.
I have to display the current state of a workflow and then allow the user to select a failed step and retry it if he/she chooses.
I'm looking for something that is as simple as possible, so preferably no Silverlight - just simple HTML and JavaScript.
The platform is ASP.NET Webforms. I don't think I can use HTML5 here - our clients don't support it.
