What am I looking at?
The chart you can see here is a web view of the comparison table, published through Visio Services. Using the controls at the top, you can choose to see a more detailed version of the comparison chart, as well as zoom in or out for a closer or wider view. To move the image within the chart window, simply click and hold, move your cursor, and release.
With Visio Services, you can publish any type of diagram (static or data-linked) to SharePoint with Enterprise features enabled so others can view the diagram without needing to have Visio installed on their machines.
