  title: Visio JavaScript Application Comments API
  description: The Visio JavaScript API enables building Office Add-ins that interact with Visio diagrams embedded in classic SharePoint Online pages. The API provides access to document elements including pages, shapes, hyperlinks, comments, shape data items, and shape views. Developers can create visual overlays, register mouse event handlers, read shape text and shape data, and control application settings. The API uses a request context and proxy object pattern with batch execution via Visio.run() and context.sync().
