19 - Map Annotations: Shapes, Part 1

📖 Task Introduction

Zooming in on the San Francisco area, your link coloring signals a relatively high number of cancellations on the routes from SFO airport (SFO) to the West Los Angeles area (BUR and LAX). Let's assume we brought the SFO -> LAX and SFO -> BUR objects into Quiver for further analysis and determined the average arrival delay time was 29 minutes.

The image below is a sketch of how that analysis flow might occur.

2. Analysis in Quiver

   

To learn more about object analysis in Quiver, you can follow the Introduction to Quiver course.

In this task, you'll use map annotations to indicate this potentially relevant data point.

🔨 Task Instructions
