Course Description

Producing high-quality, interactive visualizations historically required complex code, extensive time, and effort. Not anymore. In this course, you’ll learn how to create publication-quality graphs, harnessing the power of JavaScript, without leaving the comfort of the Python programming language we all love. You’ll create, style, and customize a variety of stunning, interactive graphs—using datasets ranging from stock prices to basketball team stats, and even penguin beak sizes! Using the Plotly charting library, you’ll also learn to customize interactivity such as hover information, range sliders, custom buttons, and even drop-downs that reactively change the visualization. Are you ready to level up your data visualization skills?

Prerequisites

Intermediate Python

Introduction to Plotly

Enter the world of Plotly! In this first chapter, you’ll learn different ways to create plots and receive an introduction to univariate plots. You’ll then build several popular plot types, including box plots and histograms, and discover how to style them using the Plotly color options.

Customizing Plots

Add to your Plotly toolkit as you explore and implement bivariate plots. Next, you’ll explore how to customize your plots to make them look amazing with annotations, hover information, legends, and custom axis titles and scales.

Advanced Customization

Take your Plotly graphs to the next level with more advanced customizations. Through hands-on exercises, you'll learn how to layer multiple interactive chart types in the same plot (such as a bar chart with a line chart over the top). You'll then create time-series selectors, such as year to date (YTD), to help you zoom in and out of your line charts.

Advanced Interactivity

In this final chapter, you'll harness Plotly's advanced user interactivity as you learn how to create buttons, dropdowns, and sliders that change everything from graph types to annotations and much more. Take your Plotly skills to the next level and build truly interactive user experiences.
