**************\* Tree Visualizer Widget**************\*

The following commands will let you load up a tree visualizer, assuming
that you have an entity loaded up named 'net':

``` {.sourceCode .javascript}
G.addWidget(GEPPETTO.Widgets.TREEVISUALISERDAT);
TreeVisualiserDAT1.setData(net);
```

Note that you can pass any node to a tree visualizer, e.g. assuming that
you have a sub entity named 'muscle\_0':

``` {.sourceCode .javascript}
TreeVisualiserDAT1.setData(net.muscle_0);
```

The properties of tree visualizer widget can be easily set as for any
other widget:

``` {.sourceCode .javascript}
TreeVisualiserDAT1.setSize(50,200);
TreeVisualiserDAT1.setPosition(100,200);
TreeVisualiserDAT1.setName("MyTree");
```

If the Model sub tree for a given aspect is empty, remember that the
model tree is not populated by default but can easily be done with the
following command (assuming an entity named 'net' containing an aspect
named 'electrical'):

``` {.sourceCode .javascript}
net.electrical.getModelTree();
```
