Altair, a versatile Python library, empowers you to craft visually compelling and interactive data visualizations. Acquiring proficiency in Altair unlocks new avenues for effectively conveying insights and narratives through data.

The course begins by introducing the concept of data storytelling and the DIKW pyramid. Then, you’ll learn why Altair is a valuable tool for developers interested in data storytelling and how it can enhance their ability to effectively communicate complex ideas. Next, the course takes a sequential approach to cover the DIKW model for data storytelling, which provides a structured framework for organizing and presenting data narratives. Finally, you’ll implement two practical use cases.

After taking this course, you’ll have acquired the skills and knowledge to build compelling data stories that combine Altair and the DIKW pyramid. You will be able to create engaging and impactful visualizations that effectively convey insights and build narratives from data.

Using Python Altair for Data Storytelling

Declarative libraries specify what you want to see, while imperative libraries specify how to build the visualization step by step.

Declarative libraries focus on manual manipulation, while imperative libraries perform automatic data transformations.

Declarative libraries use JSON for visualization, while imperative libraries use HTML5 Canvas.

Declarative libraries require extensive coding, while imperative libraries use built-in templates.
