Presentation of data object hierarchies

A device comprising:

• a memory for storing a hierarchy of data objects, wherein each data object is associated with a node type of a plurality of node types;
• and
• a processor coupled to said memory and programmed to:
• create a graphical representation of the hierarchy including a plurality of strata corresponding to the plurality of node types;
• create a plurality of tree nodes representing the data objects, each tree node associated with the node type that corresponds to the associated data object;
• position in each stratum of the plurality of strata the tree nodes associated with the node type that corresponds to the stratum;
• and
• include in the graphical representation hierarchical connectors extending between the tree nodes, wherein the hierarchical connectors represent hierarchical relationships between the data objects represented by the tree nodes.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the processor to:

• determine a node type that is associated with each data object in a hierarchy of data objects to create a plurality of node types;
• create a graphical representation of the hierarchy including a plurality of strata corresponding to the plurality of node types;
• create a plurality of tree nodes representing the data objects, each tree node associated with the node type that corresponds to the associated data object;
• positioning in each stratum of the plurality of strata, by the computing device, the tree nodes associated with the node type that corresponds to the stratum;
• and
• include in the graphical representation hierarchical connectors extending between the tree nodes, wherein the hierarchical connectors represent hierarchical relationships between the data objects represented by the tree nodes.
