Overview
The Pyramid chart allows you to view descending data. Each section represents a percentage of the lower section. For example, the first section represents the percentage of Web users who fill their shopping cart, the second section represents the percentage of those users who have validated their shopping cart and who enter their contact information, etc.
As its name suggests, it is represented in the form of a pyramid.
