FAQ

Which format should I use in a paper?

Use SVG when the journal or document workflow accepts vector images. Otherwise choose a single- or double-column preset and export a high-resolution PNG.

Does the academic preset guarantee journal compliance?

No. It provides monochrome styling and practical dimensions, but you must still check the target journal's figure requirements.

Mermaid Diagram Studio: Will the exported document look identical in every viewer?

Not always. PDF viewers, fonts, image decoders, and browser rendering can differ. Open the exported file in the software used by the recipient before distributing it.
