Data Visualization

This course is part of the UBC Certificate in Key Capabilities in Data Science.

Understand effective data visualizations and perform exploratory data analysis using Altair in Python.

By the end of the course, you’ll be able to:

• use the Altair grammar of graphics to create data visualizations
• select an appropriate visualization for the data
• perform exploratory data analysis on a dataset
• effectively communicate findings with figures
• interpret data visualizations to answer questions and formulate follow-up questions.

How am I assessed?

Each course module includes an auto-graded assignment. In weeks 5 and 8, you take an online 45-minute open-book quiz that covers materials from modules 1–4 and 5–7 respectively. In Week 8, you complete a final project using the skills you learned in the course. You must obtain an overall grade of 70% or higher, and complete the final project, to pass the course.

Expected effort

Expect to spend 8–12 hours per week to complete weekly modules, auto-graded quizzes, open-book quizzes and the final project.
