Map/diagrams with status & drill-down

Previously I used NetIQ Operations Center (formerly Managed Objects) which allowed the creation of any kind of service view using SVG drawings.  Objects for the element tree could then be mapped to any shape in the SVG drawing.  It was great for creating business process service views with drawing elements given state from monitored objects.  It's one thing I really miss in LogicMonitor, so I too would like to see something like this.  Now that most of the world is on HTML5 standards based browsers, it should be easier to implement something like this.  Visio has an SVG export so that could be a starting point.
