  Visual Analytics might be defined as data mining assisted by interactive
visual interfaces. The field has been receiving prominent consideration by
researchers, developers and the industry. The literature, however, is complex
because it involves multiple fields of knowledge and is considerably recent. In
this article we describe an initial tentative organization of the knowledge in
the field as an OWL ontology and a SKOS vocabulary. This effort might be useful
in many ways that include conceptual considerations and software
implementations. Within the results and discussions, we expose a core and an
example expansion of the conceptualization, and incorporate design issues that
enhance the expressive power of the abstraction.
