    Class CreateSVGWordCloudAction

    Action that generates SVG word clouds and tag bars from weighted word lists.

    This action provides server-side SVG generation for text visualizations, designed for AI agents and workflows to create publication-quality word clouds from data.

    // Word cloud example
    await runAction({
      ActionName: 'Create SVG Word Cloud',
      Params: [
        { Name: 'CloudType', Value: 'cloud' },
        { Name: 'Words', Value: JSON.stringify([
          { text: 'TypeScript', weight: 100 },
          { text: 'JavaScript', weight: 80 },
          { text: 'React', weight: 60 },
          { text: 'Node.js', weight: 50 }
        ]) },
        { Name: 'MaxWords', Value: '50' },
        { Name: 'Rotation', Value: 'few' },
        { Name: 'Width', Value: '800' },
        { Name: 'Height', Value: '600' }
      ]
    });

    // Tag bar example
    await runAction({
      ActionName: 'Create SVG Word Cloud',
      Params: [
        { Name: 'CloudType', Value: 'tagbar' },
        { Name: 'Words', Value: JSON.stringify([
          { text: 'AI', weight: 67 },
          { text: 'Data', weight: 45 },
          { text: 'API', weight: 32 }
        ]) },
        { Name: 'MaxWords', Value: '10' }
      ]
    });

    AuthorizesCaller: boolean

    True when the action authorizes its caller itself, so a public entry point such as the RunAction mutation may run it for an authenticated user without an MJ: Action Authorizations link. Set it only on an action that either checks an authorization the caller must hold, or reads and writes only with the caller's own permissions. Leave it false for an action that acts with more authority than its caller, or that reaches data or sends messages the caller chooses but could not otherwise reach.

    The engine reads the marker only from the class that runs, never from its parent classes. A subclass that overrides a marked action must declare the marker again.
