Field notes
The usage example calls render with Mermaid text and receives an SVG string for insertion into a page. The demos identify the tested versions as Pele 1.6.0 and Mermaid.js 12.1.0. The comparison also spells out cases where Pele may not fit: matching Mermaid.js's exact look, JavaScript click callbacks, or plugins such as ZenUML. The project is attributed to kepano and presented under the MIT license.
