diagrammia

Diagrammia is a field and practice focused on diagrams as tools for knowledge representation, communication, and reasoning. It studies how diagrams are designed, interpreted, and used to support understanding across disciplines, integrating graphic design, semiotics, cognitive psychology, and information visualization.

The term diagrammia is a neologism used in contemporary literature to describe this specific focus on diagrams beyond general data visualization. It denotes both the craft of constructing legible diagrams and the science of interpreting them as mental models.

Core activities include classifying diagram types (flow diagrams, schematics, conceptual maps, graphs), establishing design guidelines (clarity, consistency, labeled semantics, scalable layouts), and researching viewer interpretation and cognitive load. Practitioners employ sketching, diagramming software, and methodological studies to evaluate effectiveness.

In education, diagrammia supports learning by externalizing complex structures; in engineering and science, it aids process representation; in business and knowledge management, it supports decision making and documentation. It intersects with accessibility and inclusive design to ensure diagrams are legible to diverse audiences.

Ongoing challenges include avoiding oversimplification, standardizing symbols across domains, and balancing aesthetics with clarity. As multimodal communication grows, diagrammia may expand to interactive and dynamic diagrams, enabling real-time exploration of relationships.
