Sankey Charts: Visualising Movement Across Stages
Traditional charts like stacked bars can show absolute values across categories, but they fall short when it comes to highlighting how quantities move through multiple stages. You can see how much you have at each step, but not how things connect or where losses happen. It’s hard to trace the journey or spot where leads drop off.
Sankey charts fix this by mapping flows directly between stages. The width of each stream represents its volume, so conversions, drop-offs, and imbalances stand out right away. They turn detailed numbers into a clear, intuitive picture of movement.
Our Use Case: Tracking Lead Flow from Region → Channel → Outcome
This chart helps us answer a critical question:
How do leads move across regions, through channels, and into outcomes?
Key takeaways from our Sankey Chart:
Complete Flow — See the full journey of leads from start to finish in one view
Drop-offs & Bottlenecks — Instantly spot where leads are lost along the way
Channel Performance — Compare how different channels convert to outcomes
Sankey charts highlight not just the numbers, but the paths those numbers take. Instead of disconnected numbers, they reveal connections, losses, and efficiencies — making it easier to act on what matters most.
