Visualise task dependencies as directed acyclic graph (DAG)

[mountaindude]

Even if it's not recommended, client-managed Qlik Sense allows for reload task dependencies to become rather complex.
One-to-many, many-to-one, many-to-many, cyclic dependencies are all possible scenarios.

Directed Acyclic Graphs (DAGs) can handle all these scenarios and are thus a good option for visualising Sense task chains.

There are good open source libraries that can be used to render task chains visually on-screen. An embedded http server is probably used in this scenario.
Another option is to render a bitmap or vector image, possibly also creating a PDF.

This ticket is a top-level place-holder for exploring how task-chains can be visualised.
