Circular Flow Diagrams, Instantly

A circular flow diagram is a visual representation of how elements in a system connect and interact in a continuous cycle. Each node represents a component, and arrows show the direction and magnitude of flows between them. Common examples include the carbon cycle, the circular flow of income in economics, and supply chain loops.

Add nodes to represent the elements of your cycle, then define flows between them with labels and values. Customize colors, arrow styles, and font size. When you are happy with the result, download your circular diagram as a PNG or SVG, or share it with a link.

Yes — the circular flow diagram maker is completely free to use with no sign-up required. You can create, customize, and download your diagram at no cost. AI-powered generation is also available with free credits included on every account.

You can create any circular flow diagram that involves nodes and directional flows — biological cycles like the carbon or water cycle, economic circular flow models, supply chain loops, product lifecycle diagrams, and ecosystem energy flows, among others.

Yes. Describe your cycle in plain language — for example, 'Draw a circular flow diagram of the water cycle with evaporation, condensation, precipitation, and collection' — and the AI will create a complete circular diagram with nodes, flows, and labels.

In the Flows panel, click 'Add Flow', then select the source node ('From') and the target node ('To'). Add a label to describe the flow and a numeric value to represent its magnitude. Repeat for each connection in your cycle.

Absolutely. The circular flow of income diagram — showing households, firms, the government, and financial markets exchanging money, goods, and services — is a perfect use case. Add each sector as a node and define the monetary flows between them.

Yes. Toggle 'Enable Animation' in the Appearance panel to add smooth flow animation to your circular diagram. This is especially effective for web embeds and on-screen presentations where you want to highlight the continuous nature of the cycle.

Click the download button to save your circular flow diagram as a high-quality PNG or SVG image. You can also get a shareable link or use the embed code to add the diagram to any website or blog post.

Yes. Each node has its own color picker so you can assign distinct colors to different elements of your cycle. This makes it easy to differentiate sectors, organisms, or stages at a glance, especially in complex circular flow diagrams.
