The **Data Structure** widget displays the current data structure of the
pipeline, including all data groups, geometries, attribute matrices, and
data arrays that exist at a given point in the pipeline. This widget is
a good way to tell at-a-glance the current structure of your data when
clicking on filters in the pipeline.

**Drag and Drop**:

When mousing over or dragging an item from the Data Structure, selection
widgets in the **Filter Parameters** will be highlighted to display which
**Filter Parameters** can accept the target path.

In addition, because paths created by a **Filter** cannot also be its
inputs, the **Data Structure** marks which paths are new by marking it
with an astericks (|Data Structure Asterisk|) on the right side of the name. These items cannot be dragged
and will have an empty outline if they would otherwise be acceptable
inputs to a path selection widget.

Those DataObjects that are either modified (|Data Structure Modified|) or possibly deleted will also have
the appropriate icon showing next to the entry in the tree.
