Introduce the notion of model visualisation that allow to display (or export to a picture) only parts of the diagram, for example by grouping connections between two components into a single line or by providing selection lists that allow user hide some components from the view.

...
    <VisualGroup id="SomeName" visible="yes/no" />
        
    <Function ...>
        <Property name="Taste::VisualGroup" value="SomeName"/>
    </Function>
...

• Split the visibility management and the grouping?
• Top-level rects (Function,FunctionType,Comment) rendered as a united rect; the more area ­- the less Z-level, but always below regular items; no children;
• Connections use the same line only if its source and target are the same;
• No graphical editing (no editing at all?)
