This form allows visual analytics (VA) researchers and practitioners to contribute instances of symptoms, causes, remedies, and side-effects that have been identified and considered in their effort for designing, developing, evaluating, and improving VA processes, systems, and workflows. This is part of the collective effort for building a comprehensive ontology that can be used to support VA applications in the real world. We very much appreciate your contributions and will acknowledge your name and affiliation (if provided) on this page once your contribution has been included in the list of Concrete Entities. For consistency, the description of a concrete entity may be revised slightly before being included.
