Chemical Composition — Free Sunburst Chart Template
This Chemical Composition template uses a sunburst chart to break down a compound by its constituent elements, showing each element's share of the whole at a glance. The sample data maps a six-part mixture by mass percent: Carbon 45%, Oxygen 28%, Nitrogen 12%, Hydrogen 7%, Sulfur 5%, and Other 3%. It is a ready-made starting point for visualizing elemental makeup, molecular composition, or any part-to-whole scientific breakdown without building a chart from scratch.

Frequently Asked Questions
Can I replace the elements and percentages with my own data?
Yes. Click Open in editor and edit the data table directly, changing the element names (Carbon, Oxygen, etc.) and their values. Add or delete rows for any number of elements, and the sunburst redraws instantly in your browser.
Is it free, and how do I export the finished chart?
It is completely free with no signup or watermark. Once you've customized the colors and data, export your chart as a PNG, SVG, or PDF straight from the editor for use in reports, slides, or print.
