If no diagram is shown then either of the following could be the cause:

The diagram has been produced as a PDF and either no PDF viewer has been installed or the diagram has been opened in another window.
The diagram has been produced in SVG format (Scaleable Vector Graphic) and either you are using Internet Explorer version 8 or below, in this case you should install the 'Adobe SVG Viewer', or you are using another browser that does not support SVG
You are using Google Chrome browser but are viewing the report locally on a PC directly from the generated files (i.e. via the 'File' protocol) rather than via a web/HTTP server
