Coloured Modelling Spider Diagrams
While Euler Diagrams (EDs) represent sets and their relationships, Coloured Euler Diagrams (CEDs ) additionally group sets into families, and sequences of CEDs enable the presentation of their dynamic evolution. Spider Diagrams (SDs) extend EDs, permitting the additional expression of elements, relationships between elements, and set membership, whilst Modelling Spider Diagrams (MSDs ) are used to specify the admissible states and evolutions of instances of types, enabling the verification of the conformance of configurations of instances with specifications. Transformations of MSDs generate evolutions of configurations in conformity with the specification of admissible sequences. We integrate CEDs and MSDs, proposing Coloured Modelling Spider Diagrams (CMSDs), in which underlying curves represent properties of a family of sets, whether this be state-based information or generic attributes of the domain elements and colours distinguish different families of curves. Examples of CMSDs from a visual case study of a car parking model are presented.
