It is reminiscent of early commercial diagramming software, offering a straightforward interface with specialized shape libraries (called 'sheets') for different disciplines.

Dia is suited for engineers, network administrators, software developers, database designers, and students who need a free, no-frills tool for creating technical diagrams like network maps, circuit diagrams, or UML charts.
