Overview of this book

With so much data being continuously generated, developers, who can present data as impactful and interesting visualizations, are always in demand. Interactive Data Visualization with Python sharpens your data exploration skills, tells you everything there is to know about interactive data visualization in Python. You'll begin by learning how to draw various plots with Matplotlib and Seaborn, the non-interactive data visualization libraries. You'll study different types of visualizations, compare them, and find out how to select a particular type of visualization to suit your requirements. After you get a hang of the various non-interactive visualization libraries, you'll learn the principles of intuitive and persuasive data visualization, and use Bokeh and Plotly to transform your visuals into strong stories. You'll also gain insight into how interactive data and model visualization can optimize the performance of a regression model. By the end of the course, you'll have a new skill set that'll make you the go-to person for transforming data visualizations into engaging and interesting stories.

Other Interactive Plots in altair

Now that we know how to add interactivity to scatter plots, let's learn how to introduce interactivity to two other important visualization types – bar plots and heatmaps. We also encourage you to read the official documentation and look at the official example gallery at https://altair-viz.github.io/gallery/index.html to explore altair so as to be aware of the wide variety of visualization types possible in it.

Exercise 33: Adding a Zoom-In and Zoom-Out Feature and Calculating the Mean on a Static Bar Plot

In this exercise, first, we will generate a simple (static) bar plot and then explore interactivity such as zooming in and out. Then, we'll use the same bar plot and find out the mean of the Happy Planet Index of each region. We'll use the altair library here and the Happy Planet Index dataset:

  1. Import the altair module as alt:
    import altair as alt
  2. Read from the dataset:
