How to Make a Circular Diagram
From concept to finished diagram in three simple steps.
Define Your Nodes
Add each entity or stage in your cycle as a named, color-coded node. Give each one a unique ID and label.
Nodes: Atmosphere, Plants, Animals, Soil — each with a distinct color.
Add Flows Between Nodes
Connect nodes with directional flows. Set a value and optional label for each flow to show quantity or relationship strength.
Flow: Atmosphere → Plants, value 120, label 'CO₂ Absorption'.
Customize and Export
Adjust radius, font size, arrow style, and animation. Preview instantly, then download or share your circular diagram.
Export as PNG for a science report or share a live link with your team.

Circular Diagram Maker — Frequently Asked Questions
What is a circular diagram?
A circular diagram is a visualization that arranges nodes around a circle and shows directional flows or relationships between them. It is ideal for mapping cycles, ecosystems, interdependencies, and any system where entities influence each other in a loop.
How do I make a circular diagram with MakeCharts?
Open the circular diagram maker, add your nodes by entering labels and colors, then connect them with flows by specifying the source node, target node, and a value. You can also type a description and let the AI generate the diagram for you in seconds.
Can I use this as a circular flow diagram maker?
Yes. MakeCharts is built for circular flow diagrams. You can define any number of nodes and draw flows between them with directional arrows, flow values, and optional labels — making it perfect for economic models, process cycles, and system flows.
Is the circular diagram maker free?
Yes, the core circular diagram maker is completely free with no sign-up required. You can create, customize, and download circular diagrams at no cost. AI generation credits and advanced features like file upload are available on paid plans.
What is the difference between a circular diagram and a Sankey diagram?
A Sankey diagram uses horizontal flow bands to show how quantities move from one stage to another in a linear layout. A circular diagram arranges nodes in a circle and shows flows between any pair of nodes, making it better suited for cyclical systems where flows loop back to origin nodes.
