Visual Analytics with Tableau

Visual Analytics with Tableau

By: Alexander Loth

Overview of this book

Tableau is a popular data visualization tool that’s easy for individual desktop use as well as enterprise. Used by financial analysts, marketers, statisticians, business and sales leadership, and many other job roles to present data visually for easy understanding, it’s no surprise that Tableau is an essential tool in our data-driven economy. Visual Analytics with Tableau is a complete journey in Tableau visualization for a non-technical business user. You can start from zero, connect your first data, and get right into creating and publishing awesome visualizations and insightful dashboards. The book starts with an overview of Tableau, enabling you to grasp the tool’s capabilities and functions. Next, you’ll build assorted types of data visualizations in Tableau, and learn how to perform table calculations in detail. Moving ahead, you’ll work with maps, forecasts, clusters, trend lines, and learn to integrate R, Python, and MATLAB for more advanced statistical modeling. Towards the end, you’ll create interactive dashboards and share your work with others on Tableau Server, Tableau Online, and Tableau Public.

Thus, before you can even start to look at your data, you may need to start the visual analytics process with another step: data preparation. For this, Tableau offers a stand‐alone tool called Tableau Prep, which has been on the market since April 2018. Tableau Prep's functionality far exceeds the basic data‐preparation capabilities of Tableau Desktop that you saw in Chapter 2.

With a visual approach similar to that in Tableau Desktop...
