Overview of this book

Learning Tableau strengthens your command on Tableau fundamentals and builds on advanced topics. The book starts by taking you through foundational principles of Tableau. We then demonstrate various types of connections and how to work with metadata. We teach you to use a wide variety of visualizations to analyze and communicate the data, and introduce you to calculations and parameters. We then take an in-depth look at level of detail (LOD) expressions and use them to solve complex data challenges. Up next, we show table calculations, how to extend and alter default visualizations, build an interactive dashboard, and master the art of telling stories with data. This Tableau book will introduce you to visual statistical analytics capabilities, create different types of visualizations and dynamic dashboards for rich user experiences. We then move on to maps and geospatial visualization, and the new Data Model capabilities introduced in Tableau 2020.2. You will further use Tableau Prep’s ability to clean and structure data and share the stories contained in your data. By the end of this book, you will be proficient in implementing the powerful features of Tableau 2020 for decision-making.

Summary

Tableau Prep's innovative paradigm of hands-on data cleansing and shaping with instant feedback greatly extends the Tableau platform and gives you incredible control over your data. In this chapter, we considered the overall interface and how it allows you to iteratively and rapidly build out a logical flow to clean and shape data for the desired analysis or visualization.

Through a detailed, yet practical, example that was woven throughout this chapter, we explored every major transformation in Tableau Prep, from inputs to unions, joins, aggregates and pivots, to outputs. Along the way, we also examined other transformations and capabilities, including calculations, splits, merges, and the grouping of values. This gives you a foundation for molding and shaping data in any way you need.

In the next chapter, we'll conclude with some final thoughts on how you can leverage Tableau's platform to share your analysis and data stories!
