Graphical data representation

Data is represented graphically so that meaningful and comparative information can be extracted. It gives clear idea of what data represents.

  1. Pictograph - It is a representation in terms of pictures/symbols.

  1. Bar Graph - Information is displayed in terms of bars of equal width and equal gap in between. The heights are proportional to the values they represent.

  1. DoubleBar Graph - Information is displayed for two sets of data in terms of bars together. This is used for comparison of data.
