The ability to produce visualizations has become critical, increasingly sought-after. Data visualization simplifies the process of analyzing data by presenting it in a format that's easier for human brains to understand. Since our eyes are more drawn to colors and patterns than words and numbers, this tool helps communicate information much faster and efficiently using graphical representations such as charts, tables, and maps.

For example, an organization can represent its sales data with a map on top of using words and numbers. This visual map, color-coded based on the sales numbers, would help people understand how these sales increase or decrease or how the trend moves over a certain period. Data visualization is a helpful tool for every field in which data plays an important role: industries ranging from marketing to finance to tech. As a result, the ability to produce visualizations has become an important, increasingly sought-after skill for coding in today’s data analysis. This skill has also led to the rise of visualization tools, such as PowerBI, Tableau, and Looker.

This book introduces the basic concepts behind visualizations and provides examples of each in Tableau. Tableau offers step-by-step tutorials on how to create each visualization.
