This variation of the Org Chart (Static) sample uses the Overview diagram as a magnifying glass. The primary behavior of showing an observed Diagram is kept, but all other behaviors of the Overview are disabled.

### GoJS Features in this sample

#### Table Panels

The "Table" Panel, Panel.Table, arranges objects in rows and columns. Each object in a Table Panel is put into the cell indexed by the value of GraphObject.row and GraphObject.column. The panel will look at the rows and columns for all of the objects in the panel to determine how many rows and columns the table should have. More information can be found in the GoJS Intro.

#### Overview Diagrams

An Overview is a subclass of Diagram that is used to display all of the Parts of another diagram and to show where that diagram's viewport is relative to all of those parts. The user can also scroll the overviewed diagram by clicking or dragging within the overview.

The initialization of an Overview is just a matter of setting Overview.observed to refer to the Diagram that you want it to show. So there needs to be a DIV for your main diagram, for which you create a Diagram in the normal manner, and a separate DIV for your overview, for which you create the Overview in a very simple manner.
