CS 4460

CS 4460, formally known as Introduction to Information Visualization or Infovis for short, is a 3 credit hour Computer Science course about data visualization and interactivity. The course counts as both a Human-Centered Technology elective for the People thread and a Media Technologies elective for the Media thread.

The course surveys a breadth of visualization approaches and interaction methods, and outlines how the research space has evolved over time. Students learn principles of effective visual communication, implement visualizations with D3.js, and analyze and critique the merits and limitations of different visualization approaches.
