interface CallTreeRecord {
id: number;
name: string;
time: number;
children?: CallTreeRecord[];
parent_id?: number;
}Demonstrate an example icicle and sunburst visualization of an aggregated call tree.
The Icicle and Sunburst are used to visualize a hierarchical call tree
of aggregated funciton times.
Interface for how the Call Tree records are structured. The Call Tree is provided as either a tree with each node specifying its children or as a list of nodes that specify their parent. Either approach can be used, this example tests both.
interface CallTreeRecord {
id: number;
name: string;
time: number;
children?: CallTreeRecord[];
parent_id?: number;
}Sample call tree data stored inline this example for simplicity. Both alternatives of the call tree are here, either storing a root with children or a list of leaves and their parents.

data: calltree_leaves,A key accessor is required for Sunburst layers
key: (d) => d.id,This example data provides the time of each node as that node’s self time instead of
its total time. You can define either value or self_value. If you define
self_value then the layer will create a value accessor function for you that you
can use to get the total value of a node after it has been drawn.
self_value: (d) => d.time,The hierarchy can be described by the user either providing the children, children_keys_ or the _parent_key for each node. This example defaults to specifying the _parent_key_.
