Funnel charts visualize conversion or drop-off rates across sequential stages in a process. The tapered shape highlights how users, requests, or other entities decrease at each step.
Overview
Funnel charts are ideal for analyzing single, one-way processes that are standardized, long-running, and involve multiple stages. By comparing data at each stage, you can identify bottlenecks and make informed decisions. Each trapezoidal section represents the difference in volume between consecutive stages.
