***CAVEAT***

• This course is a lot of work. If you’re just looking for some easy grade, I would advise you to drop now. We have lots of people on waitlist that would like to be in class.

• If you are sincerely interested in this topic, I hope you will enjoy the course and learn a lot.

Policies

• No late homework accepted without documented personal issues (serious illness, family emergency, etc.)

• Individual HWs done individually

• Group projects are the work of your group alone – Talk to others for feedback; look at other systems for ideas; group synthesizes an

original design

• Come to class prepared by doing the readings, pay attention and participate in discussions. Doing all three regularly will earn full credit.

• Turn your smartphones off. Use laptops only for class-related work.

• Review the Georgia Tech Academic Honor Code – http://www.deanofstudents.gatech.edu/Honor/

What is Information Visualization?

• Elevator speech – Presenting data via INTERACTIVE charts, graphs, maps so that users can understand

the data, answer questions about the data and gain insights from the data

– Means is NOT just printed (static) information presentation – interaction is key element!

• Longer version – The whole course
