So this is what we’ve been working on this far with Visio.
Visio shows data from a excel sheet, saved in SharePoint. This again is connected to Visio. One row shows one boble in Visio, with a name given a collum from excel. In others words, Visio vizualizes data in excel. After that the Visio file is uploaded in a script web- part in SharePoint and the content via Visio in SharePoint.
To Summarize : Excel has the data. Visio, visualizes that data and SharePoint is the media that saves the data and hosts the presentation of Visio.
Everything in Sharepoint/Visio/excel is online ofcourse.
So.. Will you have the red or blue pill?
