Pele: Mermaid diagrams as themeable SVG

Pele is a new tool designed to simplify the creation and styling of Mermaid diagrams by converting them into themeable SVG files. Mermaid is a popular JavaScript-based diagramming and charting tool that renders Markdown-inspired text definitions into visual diagrams. Pele enhances this workflow by providing a mechanism to apply custom themes and styles to these diagrams, ensuring they align with specific design systems or brand guidelines. By outputting standard SVG files, Pele allows developers and technical writers to integrate high-quality, consistent diagrams into their documentation, websites, or presentations with greater flexibility. The tool addresses common limitations in standard Mermaid rendering, where styling options can be restrictive or difficult to manage globally. This utility is particularly useful for teams looking to maintain visual consistency across complex technical documentation while leveraging the ease of text-based diagramming.
