Abstract: A computer-implemented method of presenting an electronic document via a web browser includes maintaining on a computing device a client data model of the electronic document, the client data model comprising data that defines content of the electronic document and formatting of the content of the electronic document, and rendering a first sub-portion of content of the electronic document from the client data model to a document object model (DOM) for the web browser. The method also includes providing the DOM to the web browser, for the web browser to display a view of the electronic document from the DOM.

Abstract: A computer-implemented system, method and computer readable medium to generate graphical visualizations corresponding to a data set populated in a web-based document, such as a spreadsheet. The spreadsheet is accessible in an interne or cloud-based system, and enables users to automatically create graphical visualizations or representations based on recommendations by a spreadsheet application. The graphical visualizations may be automatically ranked such that the system provides the recommendations to the user for display. Automatic ranking is accomplished, for example, by determining data types from identifying column type, differentiating column types, and extracting data sets having attributes corresponding to various graphical visualizations.
