Rendering document views with supplemental information content

Methods and computer-readable media are provided for rendering a document view with supplemental information. A view of a document is rendered such that the document fills a canvas. The client receives a request to view a supplemental information area associated with the document. In response to the request to view the supplemental information area, a view of the document is rendered at the client such that the document does not fill the canvas. The supplemental information area is then rendered in a portion of the canvas that is not occupied by the document.
