Overview and Objectives

Topic Overview

Many aspects of society, science, business, finance, journalism, and everyday human activity, become ever more quantified. As a result, our world is awash with data of increasing amount and complexity. Still, we must keep afloat with our innate human abilities and limitations. For designers in this environment, working confidently with data becomes an essential skill. Visualization is one way to tame this information overload: well-designed representations replace difficult cognitive calculations with simpler perceptual interpretations. They can thus improve accessibility, comprehension, and memory. More literally, visualization is the process of transforming data into visuals like charts, graphs, and maps. These are then used to explore, evaluate and explain insights hidden in the data. The goal being to engage and aid diverse audiences in analytical sense and decision making.

Student Objectives

This course provides students with an introduction into the theory and practice of designing with data while keeping the human in mind. They learn the basics for creating effective data visualizations. This includes principles from graphic design, human-computer interaction, perceptual psychology, cognitive science, and statistics. We touch on the topics of data literacy, graphical encoding, visual perception, interaction, animation, narration, color, maps, networks, graphs, and text visualization. In practical exercises, students apply the tools and technologies to design and develop interactive visualizations for the web. After this course, students will be able to turn a data source into a useful, truthful, and beautiful data experience — tailored to specific information needs or communication goals.

Module Outline

The module is split into three parts:

Week 1: Data Literacy
Students learn the basics of data acquisition, mining, formatting, and statistics. They get to know a wide variety of data sources.

Week 2: Reading Week
Students read articles, watch videos, and listen to podcasts relevant to the topic of data visualization.

Week 3 – 5: Data Visualization
Students learn and apply the basics of data visualization within a group assignment to build their own interactive visualization.

Expectations and Grading

Grades will be based on group presentations, class participation, home assignments, documentation (journal) and final work. 
Contributing to constructive group feedback is an essential aspect of class participation. 
Regular attendance is required. Two or more unexcused absences will affect the final grade. Arriving late on more than one occasion will also affect the grade.

• 40% Final work
• 20% Group discussions
• 20% Journal documentation
• 10% Class participation

Any assignment that remains unfulfilled receives a failing grade.  

Deliverables

See Example below:

• Oral presentations

Students must independently prepare lectures on selected texts from the week. These can be presented in different formats. 
Possible presentation formats are:

• • Live sketching
  • Demo with prototyping
  • Slides presentation
  • etc.

The presentation should include a 3-pages written discussion, made available to the class and instructor by Friday 9am, prior to the day of the class to insure a general discussion.

The paper should include title, author, date, context, summary, bibliography.

Additional sources can be added to inform the discussion if necessary.

• Final Essay

The essay is a final 2500-words essay with a diversity of sources and bibliography (classified by genre: book, book chapter, journal article, conference article, academic thesis, newspaper article, web article, etc). 

The topic of the essay is chosen by the student and proposed by Week 8 in the form of a short paragraph (100 words) explaining the topic and the questions at stake. I will inform the student if the topic is accepted in that week. The final essay has to be submitted by Week 12.

The paper should be written in English.

• Journal/Blog

A separate 'Journal' is developed by each student that reflects on learnings from the seminar. It should be in the form of an online blog (ie. WordPress, Tumblr or other):

• The journal should be structured in a generally comprehensible manner
• The lecture notes, including annotations, are stored
• Notes, sketches for each lesson should be included as well
