  We present a novel approach to knowledge graph visualization based on
ontology design patterns. This approach relies on OPLa (Ontology Pattern
Language) annotations and on a catalogue of visual frames, which are associated
with foundational ontology design patterns. We demonstrate that this approach
significantly reduces the cognitive load required to users for visualizing and
interpreting a knowledge graph and guides the user in exploring it through
meaningful thematic paths provided by ontology patterns.
