Definition
Chart Selection is the process of choosing the graphical form most appropriate for presenting particular data or analytical results.
Human Explanation
Different questions and types of data require different charts if they are to be interpreted correctly.
Why it Matters
An unsuitable chart can conceal an important pattern, suggest a relationship that is not present or make information unnecessarily difficult to understand.
Conceptual Boundary
There is no single chart suitable for every dataset. Selection depends on the intended comparison, the structure of the data, the audience and the question the visualisation must answer.
Practical Perspective
Choose the simplest form that represents the relevant relationship accurately. Visual appeal should support readability and must not take priority over scale, context or truthful interpretation.
