Definition
Data Visualisation is the process of presenting data and analytical results in graphical form to make them easier to understand, interpret and communicate.
Human Explanation
Charts, diagrams, maps and other visual forms help people recognise patterns, comparisons and relationships that may be difficult to see in raw data.
Why it Matters
An appropriate visualisation can make information easier to understand and support faster, better-informed decisions.
Conceptual Boundary
Data Visualisation does not replace analysis and a chart is not a conclusion by itself. Visualisation presents selected data or analytical results; their meaning still depends on context and correct interpretation.
Practical Perspective
A good visualisation reduces unnecessary complexity without hiding uncertainty, omitting important context or distorting the meaning of the data. Its form should follow the analytical question and the needs of the audience.
