How it works

Describe your flow

Name the sources, intermediate nodes, and destinations. Include volumes or proportions if you have them — or describe the relative distribution in plain language.

AI builds the diagram

MyMap generates a Sankey diagram with nodes on each side and proportional bands connecting them — thicker bands represent larger flows.

Edit and share

Adjust flow values, rename nodes, or add new pathways. Export as PNG for reports, dashboards, or presentations.

الأسئلة الشائعة

Is the Sankey diagram maker free?

Yes — free to use without signing up. Free accounts include a generous number of AI messages per month. Upgrade to Pro for unlimited diagrams.

What is a Sankey diagram best used for?

Energy or material flow analysis, budget and cost allocation, website traffic attribution, marketing channel performance, supply chain visualization, and any scenario where you want to show how a total quantity splits and flows through multiple paths.

How is a Sankey diagram different from a funnel chart?

Funnel charts show a single linear reduction from top to bottom. Sankey diagrams show multi-directional flows with splits and merges — volume can branch to multiple destinations or converge from multiple sources.
