Comparisons

Comparisons are a type of data visualization that helps show the similarities and differences between different values. Types include Nightingale Rose, as pictured below in Figure (1), a Radar Chart, as pictured below in Figure (2), and a Radial Bar Chart, as pictured in Figure (5).

A Radar chart is a comparison chart in which data is plotted on a radial grid. The grid is split into equal increments, typically from 0 to 100, in which multiple points can be graphed. While similar to the Nightingale Rose chart in those respects, the Radar Chart is different in that multiple sets of data can be plotted and analyzed within it at the same time. For example, Figure (3) below shows the responses from different customers regarding how important each aspect of a new phone is to each of them, from 0 to 100. On the Radar Chart shown in Figure (2), it is shown how each of the 3 customer's responses are plotted at the same time. This is commonly used in video games in order to show the balance of certain traits of characters!
