Overview of this book

Data analysis enables you to generate value from small and big data by discovering new patterns and trends, and Python is one of the most popular tools for analyzing a wide variety of data. With this book, you’ll get up and running using Python for data analysis by exploring the different phases and methodologies used in data analysis and learning how to use modern libraries from the Python ecosystem to create efficient data pipelines. Starting with the essential statistical and data analysis fundamentals using Python, you’ll perform complex data analysis and modeling, data manipulation, data cleaning, and data visualization using easy-to-follow examples. You’ll then understand how to conduct time series analysis and signal processing using ARMA models. As you advance, you’ll get to grips with smart processing and data analytics using machine learning algorithms such as regression, classification, Principal Component Analysis (PCA), and clustering. In the concluding chapters, you’ll work on real-world examples to analyze textual and image data using natural language processing (NLP) and image analytics techniques, respectively. Finally, the book will demonstrate parallel computing using Dask. By the end of this data analysis book, you’ll be equipped with the skills you need to prepare data for analysis and create meaningful data visualizations for forecasting values from data.

Interactive visualization with Bokeh

Bokeh is an interactive, high-quality, versatile, focused, and more powerful visualization library for large-volume and streaming data. It offers interactive, rich charts, plots, layouts, and dashboards for modern web browsers. Its output can be mapped to a notebook, HTML, or server.

Both the Matplotlib and Bokeh libraries have different intentions. Matplotlib focuses on static, simple, and fast visualization while Bokeh focuses on highly interactive, dynamic, web-based, and quality visualization. Matplotlib is generally used for publication images while Bokeh is for a web audience. In the remaining sections of this chapter, we will learn basic plotting using Bokeh. We can create more interactive visuals for data exploration using Bokeh.

The simplest way to install the Bokeh library is with the Anaconda distribution package. To install Bokeh, use the following command:

conda install bokeh

We can also install it using pip. To install Bokeh using pip...
