.. attribute:: name: str
    The name of a group of tasks.
    For a task like ``("x-123", 0)`` this is the text ``"x-123"``
.. attribute:: states: Dict[str, int]
    The number of tasks in each state,
    like ``{"memory": 10, "processing": 3, "released": 4, ...}``
.. attribute:: dependencies: Set[TaskGroup]
    The other TaskGroups on which this one depends
.. attribute:: nbytes_total: int
    The total number of bytes that this task group has produced
.. attribute:: duration: float
    The total amount of time spent on all tasks in this TaskGroup
.. attribute:: types: Set[str]
    The result types of this TaskGroup
.. attribute:: last_worker: WorkerState
    The worker most recently assigned a task from this group, or None when the group
    is not identified to be root-like by `SchedulerState.decide_worker`.
.. attribute:: last_worker_tasks_left: int

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
