Also, can I nudge you into using <link/> to expose links to the data 
sources behind the visualizations? A SPARQL Construct or Describe URLs 
will do. You can see examples of what I mean via URI Debugger output below:

- Linked Data Description (Green Page)

- Linked Data Description (Blue Page -- which leverages 
.well-known/host-meta for discoverable URL templates etc..) .

Goal is to loosen the coupling between the visualization and its data 
sources in a Web user agent friendly way.
