Harvard online course in Data Visualization

Harvard School of Engineering & Applied Science has an online course open to the public on Data Visualization.

It was produced in Spring 2013 & still has an online repository of all the lectures, labs & workshops that took place. You can go through the entire semester’s worth of content — including how to use the D3 Javascript library to visualize data in interactive ways.

The amount and complexity of information produced in science, engineering, business, and everyday human activity is increasing at staggering rates. The goal of this course is to expose you to visual representation methods and techniques that increase the understanding of complex data. Good visualizations not only present a visual interpretation of data, but do so by improving comprehension, communication, and decision making.

In this course you will learn how the human visual system processes and perceives images, good design practices for visualization, tools for visualization of data from a variety of fields, collecting data from web sites with Python, and programming of interactive web-based visualizations using D3.
