This is cool! One use case is generating a Mermaid diagram as an image. For example, you can use the following HTML[^1]:

  <!doctype html>
  <html lang="en">
    <body>
      <pre class="mermaid">
    graph LR
        A --- B
        B-->C[fa:fa-ban forbidden]
        B-->D(fa:fa-spinner);
      </pre>
      <script type="module">
        import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@11/dist/mermaid.esm.min.mjs';
      </script>
    </body>
  </html>

Then html2png.dev will serve you:
