Lecture/lab: Tues-Thurs 10:00-11:50 Ellings Studio 2611

Course concentration on fundamentals of data visualization and design, with an emphasis on data query, analysis, processing and visualization in linear, 2D frequency, and spatial map visualizations.

Data mining, Knowledge Discovery, Culture Analytics through MySQL
Goals: Discover unexpected, interesting patterns in a large dataset
Source: 90 million datasets of library check-outs/check-ins, Seattle Public Library source

2D Frequency Data Mapping - Visual Language Basics with Processing
Goals: Acquire visual language basics, visualize data in java-based Processing
Source: 90 million datasets of library check-outs/check-ins, Seattle Public Library source

3D Interactive Visualization
Goals: Design in 3D, interactive space, implement algorithms in java-based Processing
Source: 90 million datasets of library check-outs/check-ins, Seattle Public Library source

Final Student Project
Goals: Student defined project building on skills acquired through previous assignments
Source: Student determined
