Sunburst Diagram Maker

A sunburst diagram is a radial chart that displays hierarchical data as a series of concentric rings. Each ring represents a level in the hierarchy, and each arc segment's size reflects its value relative to siblings. It is ideal for showing part-to-whole relationships across multiple levels simultaneously.

Enter your root node name, then add child nodes and assign values using the tree editor. Alternatively, describe your hierarchy to the AI and it builds the structure for you. Adjust colors and labels in the configuration panel, then export or share your diagram.

Yes. MakeCharts lets you create and export sunburst diagrams at no cost and with no account required. Free AI credits are included so you can try AI-powered generation immediately. Paid plans unlock higher AI usage limits, CSV upload, and embed codes.

Both visualize hierarchical data, but a sunburst diagram arranges levels as concentric rings radiating from a center, while a treemap uses nested rectangles. Sunburst diagrams are better for showing multi-level parent-child relationships in a radial layout, while treemaps emphasize proportional area within a rectangular space.

MakeCharts supports as many hierarchy levels as your data requires. Each level is rendered as an additional outer ring. For readability, most effective sunburst diagrams use between two and five levels, but there is no hard limit in the tool.

Yes. You can define a custom color palette and choose between two color modes: 'By category' applies colors based on root-level segments, and 'By level' applies a distinct color to each ring depth. Both modes help distinguish segments clearly.

You can paste data directly from Excel or Google Sheets into the editor and map it to your hierarchy manually. Pro users can upload CSV or Excel files directly. The AI can also read a pasted table and generate the sunburst hierarchy automatically.

Yes. Plus and Pro plans include embed codes that let you add a responsive sunburst diagram to any webpage. The chart renders cleanly on all screen sizes without additional configuration.

MakeCharts is a fully visual, no-code sunburst chart generator. You build and customize your diagram through point-and-click controls or by describing it to the AI. No programming, no spreadsheet formulas, and no design software required.

You can export sunburst diagrams as PNG for use in presentations and documents, or as SVG for scalable, print-ready output. SVG files can also be imported into design tools like Figma or Adobe Illustrator for further refinement.
