Diagrammatically focuses on the role of diagramming in urban design practice and processes. Diagrams are particularly useful in urban design practice during times of transition. While architectural renderings tend to depict an idealized end state, diagrams can be used to divulge and explore the uncertainty inherent in urban conditions. Diagrammatically presents numerous diagramming approaches that reveal, analyze, and ultimately aim to improve the design of cities. Diagrammatically is the 5th volume in the Cleveland Urban Design Collaborative's Urban Infill journal series.
