Metrics offer an objective assessment of the inner fabrics of ontologies. They allow us to quickly understand graph properties, logical complexity, completeness of human-centered annotations, or degree of interconnection. When analyzed historically, ontology metrics tell much about development decisions and the impact of changes and can be used for quality control measures. The NEOntometrics software allows calculating evolutional ontology metrics for git-based repositories and implements the majority of literature-proposed metric frameworks. This paper presents the recently added visualization capabilities for visualizing the differences between ontologies in a repository, assessing the change impact of the most recent commit, and examining ontology evolution.
