Maintaining graphical presentations based on user customizations

A system for rendering graphics for display on a display screen, the system comprising:

• a processor for executing computer executable instructions;
• and
• computer storage media storing computer executable instructions that when executed provide:
• a plurality of possible graphic definitions, each of the possible graphic definitions specifying default properties for associated graphics operable to represent content;
• a customization engine operable to create a first graphical hierarchical diagram corresponding to a first graphic definition and a second graphical hierarchical diagram corresponding to a second graphic definition such that the first graphical hierarchical diagram and the second graphical hierarchical diagram have similar properties;
• and
• a user interface presenting a graphical representation for each of the plurality of possible graphic definitions for selection by a user, the user interface including:
• a content pane for receiving input from the user and displaying the content for editing by the user;
• a graphics pane allowing visualization and editing of graphical content;
• a gallery pane presenting the plurality of possible graphic definitions;
• wherein:
• in response to selection of the first graphical representation associated with the first graphic definition, displaying the first graphical hierarchical diagram on the display screen as defined by the customization engine;
• in response to receiving a first customization to a presentation property associated with the graphical content in the graphics pane, updating the presentation property with the first customization in the first graphical hierarchical diagram;
• in response to receiving a second customization to a semantic property associated with the graphical content in the graphics pane, updating the semantic property with the second customization in the first graphical hierarchical diagram;
• and
• in response to selection of the second graphical representation associated with the second graphic definition, wherein the second graphic definition does not comprise the first customization and the second customization, displaying the second graphical hierarchical diagram comprising graphical content that includes the updated semantic property but not the updated presentation property.

A computer-implemented method for rendering one or more graphical diagrams for display by a display device, the method comprising:

• receiving content text to be visually represented in a first graphical diagram in a content pane;
• receiving selection of a first graphic definition for rendering the first graphical diagram from a gallery pane, the first graphic definition specifying a first graphical element;
• rendering the first graphical diagram in a drawing pane on the display device based on the content text and the first graphic definition, the first graphical diagram comprising the content text within the first graphical element;
• in response to receiving a change to the content text, updating graphical text in the first graphical element of the first graphical diagram;
• in response to receiving a change to a presentation property of the first graphical element, updating the presentation property in the first graphical element;
• in response to receiving a change to a semantic property of the first graphical element, updating the semantic property in the first graphical element;
• and
• in response to receiving a selection of a second graphic definition for rendering a second graphical diagram specifying a second graphical element, wherein the second graphic definition does not comprise the updated semantic property and the updated presentation property, rendering the second graphical diagram including the updated graphical text and the updated semantic property but not the updated presentation property in the second graphical element.
