What does a funnel chart tell me?

It shows how many people remain at each ordered stage of a process and, crucially, where the biggest drop-offs happen — so you can focus optimisation on the step losing the most users.

When is a funnel the wrong choice?

When stages aren't strictly sequential or the count can increase between steps. For comparing conversion rates across segments, a grouped bar chart of the rates is usually clearer than overlaid funnels.

Understanding Funnel charts

Funnel charts show how a population shrinks across the ordered stages of a process — visitors to signups to activated to paying — making each drop-off step visible so you can see where you lose people.

Vireya colours each stage from your palette and labels stage names and counts directly.

When to use

Conversion or acquisition funnels with sequential, narrowing stages.
Any monotonically decreasing process (application → interview → offer → hire).
Highlighting the biggest drop-off step for optimisation.

When to avoid

Stages that aren't strictly ordered or don't only decrease.
Comparing funnels across segments — small multiples read better.
When exact step-to-step conversion rates matter more than shape (use a bar chart of rates).

Best practices

Keep stages in true process order, top to bottom.
Label each stage with its absolute count and conversion from the previous step.
Limit to the stages that matter — too many segments flatten the signal.

Accessibility

Show stage names and counts as text, not colour-only.
Provide step-to-step conversion rates in a tooltip or table.
