The following are the cardinal points of difference between a tubular, and a diagrammatic representation of data:
(i) Visual appeal: The tabular presentation of data does not have any visual appeal whereas the diagrammatic presentation of data has a visual appeal, and as such, it proves to be more impressive for a layman.
(ii) Nature of information: The tabular presentation of data provides information in a precised manner. Whereas the diagrammatic presentation provides the information in an approximate manner.
(iii) Nature of reading for interpretation: Tabular presentation needs closer, and intensive reading for making purposeful interpretation of the data, whereas diagrammatic presentation does not need so.
(iv) Number of Information: In tabular representation of data more than one type of information relation to the problem can be exhibited easily. But in diagrammatic representation of data only one type of information can be presented clearly. However, in certain diagrams, information relation to the different components of the main information can be displayed.
