Overview of this book

Do you want to transform data into captivating images? Do you want to make it easy for your audience to process and understand the patterns, trends, and relationships hidden within your data? The Data Visualization Workshop will guide you through the world of data visualization and help you to unlock simple secrets for transforming data into meaningful visuals with the help of exciting exercises and activities. Starting with an introduction to data visualization, this book shows you how to first prepare raw data for visualization using NumPy and pandas operations. As you progress, you’ll use plotting techniques, such as comparison and distribution, to identify relationships and similarities between datasets. You’ll then work through practical exercises to simplify the process of creating visualizations using Python plotting libraries such as Matplotlib and Seaborn. If you’ve ever wondered how popular companies like Uber and Airbnb use geoplotlib for geographical visualizations, this book has got you covered, helping you analyze and understand the process effectively. Finally, you’ll use the Bokeh library to create dynamic visualizations that can be integrated into any web page. By the end of this workshop, you’ll have learned how to present engaging mission-critical insights by creating impactful visualizations with real-world data.

7. Combining What We Have Learned


Bokeh is an interactive visualization library focused on modern browsers and the web. Other than Matplotlib or geoplotlib, the plots and visualizations we are going to create in this chapter will be based on JavaScript widgets. Bokeh allows us to create visually appealing plots and graphs nearly out of the box without much styling. In addition to that, it helps us construct performant interactive dashboards based on large static datasets or even streaming data.

Bokeh has been around since 2013, with version 1.4.0 being released in November 2019. It targets modern web browsers to present interactive visualizations to users rather than static images. The following are some of the features of Bokeh:

  • Simple visualizations: Through its different interfaces, it targets users of many skill levels, providing an API for quick and straightforward visualizations as well as more complex and extremely customizable ones.
  • Excellent animated visualizations: It provides...
