Different Ways to Visualise Data
The following are some of the different ways to visualise data:
Data Visualisation Technique 1
Name of the Representation Bar Graphs
Description Graph that represents categorical data with rectangular bars with heights
and length proportional to the values that they represent.
How to draw?

Two Wheelers 174.16
Three Wheelers 6.37
Commercial Vehicles 7.18
Passenger Vehicles 27.74
0.00 50.00 100.00 150.00 200.00
Suitable for which type of data? It is used to compare things between different groups or to track changes
over time. For example, marks of 5 subjects to compare, rise in population
in five years and changing fuel price every month.
Data Visualisation Technique 2
Name of the Representation Histogram
Description Graphs are similar to Bar Graphs, that represent categorical data with
rectangular bars with heights and length proportional to the values that
they represent placed grouped together.
