A swift and practical introduction to building interactive data visualization apps in Python, known as dashboards. You’ve seen dashboards before; think election result visualizations you can update in real time, or population maps you can filter by demographic. With the Python Dash library you’ll create analytic dashboards that present data in effective, usable, elegant ways in just a few lines of code.

The book is fast-paced and caters to those entirely new to dashboards. It will talk you through the necessary software, then get straight into building the dashboards themselves. You’ll learn the basic format of a Dash app by building a twitter analysis dashboard that maps the number of likes certain accounts gained over time. You’ll build up skills through three more sophisticated projects. The first is a global analysis app that compares country data in three areas: the percentage of a population using the internet, percentage of parliament seats held by women, and CO2 emissions. You’ll then build an investment portfolio dashboard, and an app that allows you to visualize and explore machine learning algorithms.

In this book you will:

  • Create and run your first Dash apps
  • Use the pandas library to manipulate and analyze social media data
  • Use Git to download and build on existing apps written by the pros
  • Visualize machine learning models in your apps
  • Create and manipulate statistical and scientific charts and maps using Plotly

Dash combines several technologies to get you building dashboards quickly and efficiently. This book will do the same.

"The bottom line is that [The Book of Dash] . . . is a convenient quick introduction that paves the way for Python programmers who are faced with the task of realizing a dashboard."
—Tam Hanna, Founder of Tamoggemon Software

“Very easy to understand . . . You can sense that the authors want to share their knowledge. . . . Overall [The Book of Dash] is an amazing book that data analysts must have when working with Python.”
—Tânia Frazão, Python Coder

“[The Book of Dash] fills the void of becoming master in Plotly Dash and Dashboards.”
—Sanjeev Sharma, Python Coder

“With [The Book of Dash], the authors have provided some great examples showing how easy and quickly it is to get a visualization up and running with just a few tools. While the book requires some familiarity with Python, it provides a refresher on basic programming topics in the first couple of chapters, then jumps into the topic at hand with some easy-to-follow examples. I’m looking forward to developing some of my own visual apps with what I’ve learned.”
—Scott Chouinard, Senior Gaming Analyst, Service Nova Scotia

"The understanding of Dash I gained in this book provided me with a whole new way to analyze and visualize data.”
—Jordan Marshal, Python Developer

“Just the book I’ve been looking for. This is the perfect next step for any Python student seeking to pivot into the Data Science niche. Easy to follow, and practical examples left me with the confidence to start on my own projects. Highly recommended.”
—Peter Rubio, Python Author

"My journey with Dash began when I stumbled upon one of Adam's videos by accident. After a lot of trial and error and digging through pages of documentation and blog posts, this is the book I wish I had when I first started. It is thorough and covers quite a number of often challenging topics and techniques with ease."
—Brad Bartram, Founder of Darksbian Data Services
