A chart is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart". A chart can represent tabular numeric data, functions or some kinds of qualitative structure and provides different info. The term "chart" as a graphical representation of data has multiple meanings: A data chart is a type of diagram or graph, that organizes and represents a set of numerical or qualitative data. Other domain specific constructs are sometimes called charts, such as the chord chart in music notation or a r ...


A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since ancient times, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word graph is sometimes used as a synonym for diagram.


20-sim is commercial modeling and simulation program for multi-domain dynamic systems, which is developed by Controllab. With 20-sim models can be entered as equations, block diagrams, bond graphs and physical components. 20-sim is widely used for modeling complex multi-domain systems and the development of control systems.

Activity cycle diagram

There are many known modeling paradigms to describe the dynamics of system in process-oriented, event-based and activity-based view points. Among those modeling paradigms, the activity-based modeling is a natural way to represent the activity paradigm of discrete event simulation and our knowledge about a system. In activity-based modeling, the dynamics of system is represented as an ACD which is a network model of the logical and temporal relationships among the activities. An ACD is easily implemented with the activity scanning method of simulation execution.

Aircraft seat map

An aircraft seat map or seating chart, is a diagram of the seat layout inside a passenger airliner. They are often published by airlines for informational purposes, and are of use to passengers for selection of their seat at booking or check-in. Seat maps usually indicate the basic seating layout, the numbering and lettering of the seats, the location of the emergency exits, lavatories, galleys, bulkheads and wings. Airlines which allow internet check-in frequently present a seat map indicating free and occupied seats to the passenger so that they select their seat from it. In addition to ...

Alluvial diagram

Alluvial diagrams are a type of flow diagram originally developed to represent changes in network structure over time. In allusion to both their visual appearance and their emphasis on flow, alluvial diagrams are named after alluvial fans that are naturally formed by the soil deposited from streaming water.
