Overview of this book

Hands-On Data Preprocessing is a primer on the best data cleaning and preprocessing techniques, written by an expert who’s developed college-level courses on data preprocessing and related subjects. With this book, you’ll be equipped with the optimum data preprocessing techniques from multiple perspectives, ensuring that you get the best possible insights from your data. You'll learn about different technical and analytical aspects of data preprocessing – data collection, data cleaning, data integration, data reduction, and data transformation – and get to grips with implementing them using the open source Python programming environment. The hands-on examples and easy-to-follow chapters will help you gain a comprehensive articulation of data preprocessing, its whys and hows, and identify opportunities where data analytics could lead to more effective decision making. As you progress through the chapters, you’ll also understand the role of data management systems and technologies for effective analytics and how to use APIs to pull data. By the end of this Python data preprocessing book, you'll be able to use Python to read, manipulate, and analyze data; perform data cleaning, integration, reduction, and transformation techniques, and handle outliers or missing values to effectively prepare data for analytic tools.

Chapter 5: Data Visualization

Being able to visualize data is the backbone of data analysis. The area of data visualization is very exciting, as there are endless possibilities for novelty and creativity in drawing visualizations that tell better stories about your data. However, the core mechanisms of even the most innovative graphs are similar. In this chapter, we will cover these fundamental mechanisms of visualizations that give life to the data and allow us to compare, analyze, and see patterns in it.

As you will learn these fundamental mechanisms, you will also be developing a better backbone/skillset for your data preprocessing goals. If you can fully understand the connection between the data and its visualizations, you will be more effective at preprocessing data for effective visuals. In this chapter, you will work with the data that I have already preprocessed, but in later chapters, we will cover the concepts and techniques that lead to these preprocessed datasets.
