Visualizing metadata element sets in side deliverable -- quite urgent feedback request

Dear all,

Among the TODOs to clean at the last moment for the side deliverable, there is one on visualizing Metadata Element Sets:

The original idea was to show the relations between Sets and their relative importance (as indicated by their usage in individual cases).
The inspiration was Mondeca's Linked Open Vocabularies: we wanted to do the same kind of graph as http://labs.mondeca.com/dataset/lov/details/vocabularySpace_Library.html, but
- based on our use cases  only
- with links between element sets, as in http://labs.mondeca.com/dataset/lov/details/vocabulary_skos.html

There was even a mock-up:
Unfortunately, it has obvious that the editors of the side deliverable don't have enough resources to gather the data needed to create this: Mondeca's scripts use a SPARQL endpoint, for which we'd have to create fairly rich data.

BUT as I was about to remove the mock-up, I saw that the site Paul Walk has made in Pittsburgh was still alive: http://www.paulwalk.net/lldvis/
Even better, I've discovered that:
1. I can easily remove from this page the value vocabularies, keeping the element sets only
2. I can add new element sets, fitting the latest version of our side deliverable. In fact we can really add them in the data behind Paul's page, and attach use cases to them. But perhaps that's not needed, we can tweak the size of the tags manually...

So I've implemented step 1 and created a tag cloud for the metadata element sets:

It's clearly not the full monty we were dreaming of, but it still gives some idea on usage of element sets.And it's really easy to make.
I could continue this, adding the element sets we miss. And then take a screenshot to be included in the side deliverable: I'm afraid we can't fit in the real HTML code, as it is heavily depending on scripts that are on Paul's site.

Do you think that would be worth it? And it's not too late?
