The core UMBEL ontology now contains about 34,000 reference concepts organized according to 31 super types. There are more than 65,000 relationships amongst these concepts, resulting in a graph structure of very large size.

It is difficult to grasp this graph in the abstract. Thus, using methods earlier described in our use of the Gephi visualization software [1], we present below a dynamic, navigable rendering of this graph of UMBEL core:

**Note**: at standard resolution, if this graph were to be rendered in actual size, it would be larger than 34 feet by 34 feet square at full zoom !!! Hint: that is about 1200 square feet, or 1/2 the size of a typical American house !

You may also want to inspect a larger version of this big graph by downloading its PDF.
