Overview

Looker is a modern data platform in Google Cloud that lets you analyze and visualize your data interactively. You can use Looker to do in-depth data analysis, integrate insights across different data sources, build actionable data-driven workflows, and create custom data applications. With Looker and Google Cloud, you can deliver actionable business insights at the point of decision, create new value streams, and infuse data into products and workflows to move the business forward.

In this lab, you learn how to use Looker to query sorted and filtered data, create Looks, and add them to a Dashboard. For this lab, an Explore of the Federal Aviation Administration's (FAA) Airport data has been created for you. This dataset contains information on different attributes of airports such as city, date of commission, facility type, etc.

You can learn more about creating Explores from the Exploring data in Looker documentation.

What you'll learn

In this lab, you learn how to:

• Use filters to select desired data from Dimensions and Measures
• Create table visualizations on sorted and filtered data
• Save Explore queries as Looks
• Add Looks to a dashboard

Setup and requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.

This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.

To complete this lab, you need:

• Access to a standard internet browser (Chrome browser recommended).

• Time to complete the lab---remember, once you start, you cannot pause a lab.

How to start your lab and sign in to Looker

1. When ready, click .

   A new panel will appear with the temporary credentials that you must use for this lab.

   If you need to pay for the lab, a pop-up will open for you to select your payment method.
