How to Represent Data with Intelligent Use of the Coordinate System

This is a guest repost by Jacob Joseph from CleverTap. Basically, Cartesian coordinate system uses a grid of straight lines while Polar coordinate system uses a grid of circles to represent data. Let's now look at a few examples where with the appropriate use of the systems discussed above, we will able to visualize different aspects of the data. The standard graphic visualization for a categorical variable is bar charts. Bar charts are useful if you are dealing with a low number of categories within a variable.
