Frequently asked questions
Can I create charts for free without signing up?
Yes. All 36 makers work without an account or subscription. PNG and SVG exports do not add watermarks.
How can I keep editing my chart in Figma?
Download SVG to preserve vector shapes and colors. PNG is an image for sharing or inserting; it does not let you edit each shape separately.
