📖 Task Introduction

Another set of figures you’d like represented in your canvas is the departure delay on this flight alert and the average departure delay for flights on this route. This path introduces some additional complexity, but we’ll explore some of Quiver’s features for easily following the logical flow of your analysis.

As you proceed, you’ll want to bear in mind the underlying links between the applicable Ontology object types:
