5. Interactive Visualization of Data across Time

Learning Objectives

By the end of this chapter, you will be able to:

Explain temporal data and how it is used in the real world
Use pandas to manipulate time-series data
Build basic interactive plots by adding custom buttons and a range slider to better represent time-series data with the Bokeh library
Use custom aggregators on time-series plots to explain the behavior of data

In this chapter, we will explore the interactive visualization of data across time.

Introduction

In the previous chapters, we learned how to create interactive visualizations to represent data in different contexts, such as creating bar plots for stratified data. In this chapter, we will learn how to create interactive ...
