Enrichment wheel chart

[mmaltsev]

I implemented a wheel chart as a tool to detect changes in the STO after the enrichment process. In particular, you can see there:

1. Subject-predicate tuples that were enriched with new objects (blue nodes).
2. Predicates that subject was enriched with after the enrichment (green nodes).
3. Untouched during the enrichment process subject-predicate tuples (gray nodes).

In the future the user will be able to navigate online through all the standards and standard organizations for such information.
Irlán, can you provide any feedback regarding this feature, please?

Looks fine. Would be possible to know, for those that were enriched, which are the values? Also, which are the numbers?
Can you create a legend for the colors?
