Funnel & Pyramid
The funnel chart is used to show progressive reduction of data as it passes from one phase to another. It is most widely used to show sales conversion rates - starting from the number of leads you got, you move to the number of leads you could you qualify and finally the closure stage. Using the funnel, it is easy to identify the stage where most leaks are happening which can then be worked on. You can also use it to visualize the recruitment process in your organization and website visitor trends.
