FAQ
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.
Can I create a circular economy diagram with this tool?
Absolutely. The circular diagram maker is well-suited for circular economy visualizations. You can map how materials, products, and waste flow between production, use, recycling, and recovery stages, with labeled flows and weighted values to show relative quantities.
How many nodes and flows can I add?
You can add as many nodes and flows as your diagram needs. For readability, most effective circular diagrams use between 4 and 12 nodes. You can adjust the diagram radius and font size to keep labels legible as the complexity grows.
Can I animate my circular diagram?
Yes. Enable the 'Animation' toggle in the Appearance panel to add animated flow lines to your diagram. This is especially useful for presentations where you want to highlight the direction and movement of flows between nodes.
What file formats can I download my circular diagram in?
You can download your circular diagram as a high-resolution PNG for use in documents, slides, and social media. SVG export is also available, giving you a lossless vector format suitable for web use and print publications.
Does MakeCharts work on mobile for making circular diagrams?
Yes. MakeCharts is fully responsive and works on smartphones and tablets. You can create and edit circular diagrams on any device, though a desktop or tablet gives you more workspace for managing multiple nodes and flows.
