Hi Mark,
there are several examples of WebRatio Dashboards made with BPMN, as the one described in the following success story:
http://www.webratio.com/documents/SuccessStory_SET_EN.pdf .
Please, can you describe what kind of data sets do you want to monitor and view through the Dashboard?
Contact me at paolo.riviello@webratio.com and I'll send you an extensive paper describing the BPM project of the success story above.
Regards,
Paolo
