Specifies the ordering policies for child nodes under the same parent in a TreeLayout.
Remarks
This enumeration provides different strategies for ordering child nodes around their parent node. Each policy affects how child nodes are positioned relative to each other, impacting the overall appearance and compactness of the layout. The ordering strategies include arranging nodes based on subtree sizes, wedge angles, or preserving the original order.

Constants
The actual area of a subtree is used as the subtree size. The smallest subtree is placed next to the largest subtree, followed by the second smallest subtree and so on. This way, drawings can become more compact, because the adjacent placement of large subtrees is avoided (which would require edges to become longer for subtrees to fit next to each other).

API
- childOrderingPolicy
The node with the greatest angle gets median position in the sorting order. The smaller the wedges, the farther away a node will be placed from the median position. Using this policy, the produced results are often more symmetric.

Static Methods
Converts the given argument to an enum constant of this enum type.
Converts the given argument to an enum constant of this enum type.
Most notably, this method can convert an enum constant's name into the enum constant itself.

Parameters
- value: ChildOrderingPolicy
- The value to convert to an enum constant.
Return Value
- ChildOrderingPolicy
- The enum constant that corresponds to the given argument.
Returns the name of the given enum constant.
Returns the name of the given enum constant.
static
Parameters
- value: ChildOrderingPolicy
- The numeric value of an enum constant.
Return Value
- string
- The name of the enum constant.
Throws
- Exception ({ name: 'Error' })
- If this type is a flags enums, and the provided value doesn't correspond to a single enum constant, or if this enum type contains no constant of the given numeric value.
