Funnel charts display progressively decreasing values across stages, ideal for visualising conversion processes and multi-stage workflows.

​
When to use

  • Conversion funnels - Track user journey from awareness to conversion
  • Process stages - Show drop-off at each step
  • Progressive reduction - Display sequential filtering or narrowing

​
Basic example

const config: GraphConfig = {
  type: 'funnel',
  data: {
    columns: [
      { key: 'stage', label: 'Stage' },
      { key: 'users', label: 'Users' }
    ],
    rows: [
      { stage: 'Website visits', users: 10000 },
      { stage: 'Product views', users: 5000 },
      { stage: 'Add to cart', users: 2000 },
      { stage: 'Checkout', users: 800 },
      { stage: 'Purchase', users: 500 }
    ]
  }
};

​
Conversion rate

Show the conversion rate between the first and last stages as a headline number: 
const config: GraphConfig = {
  type: 'funnel',
  headlineNumbers: {
    show: 'conversion'
  },
  data: { /* ... */ }
};
The 'conversion' headline number type is specifically designed for funnel charts. It calculates the ratio between the first and last values.

​
Stage data

The funnel automatically calculates drop-off between stages. Your data should include:
  • First column: Stage names (categorical)
  • Second column: Values (numeric), ordered from highest to lowest
