4. Data Exploration: Comparison and Composition

Overview

In this chapter, you will create your first chart in Tableau and work through some basic and intermediate charts, such as tree maps, bar-in-bar charts, and stacked area charts. You will learn how to choose the optimal chart for a given scenario, look at the best ways to create a trend report, and explore comparisons across measures (using bar-in-bar and bullet charts). Then, in this lesson's final activity, you will put all you've learned into practice by analyzing data from Singapore's vehicle population audits over the past decade. By the end of this chapter, you will be familiar with working with bar charts, area charts, and Marks cards, which are used to add contextual detail to charts and views.
