 Thanks. I am going to run a test on that next week.

 I like "VisEc"

  Sure but you pointed out the trademark issue.

 but find "VizEc" a little confusing as there is no "z" in "Visual".

  I understand. Generally, the term visual is rather general, as web
  sites usually are visual. Maybe we can come up with somewhat more
  specific on what exactly the site likes to show, like relationships
  RelEc, or just graphics GraphEc.
