The Week in Vis: Week 14 (Dec 5-9): Graphs

in Weeks in Vis

The last full week of the semester!

In some ways, this is a normal week. We have a big topic (graphs - in the sense of networks, not in the sense of “line graph”). But, since you’re probably deep into the project, we’ll adjust expectations accordingly.

To give you more time to focus on the project, we won’t have an online discussion this week. Instead, use this as an opportunity to contribute to the Project Theme Discussions. Please be careful though: join a group before posting (if you post before joining a group, it goes into a “no-mans-land” where only people who haven’t joined a group can see it).

The Week in Vis: Week 13 (Nov 28-Dec2): Evaluation

in Weeks in Vis

The week after Thanksgiving… we can sortof get back to a normal schedule.

This topic for this week is Evaluation. I’ll talk about it in lecture on Monday. The readings are important. You can read them before lecture or after (I’ll go through the main points - it’s stuff you will need to see more than once). The readings are very reduced for the project. But, there will be a “Design Excercise” related to both the project and the readings for the following week.

For Wednesday’s lecture, the topic is “the random stuff that doesn’t fit anywhere else.” It might be more on evaluation. I may talk about 3D and animation - because there is simply no other day to talk about them, and I feel a need to talk about them. Or maybe I’ll talk about the SciVis topics that we simply don’t get time to cover in class, but I feel must be at least mentioned in a Vis class.

In terms of the project: there is a “check in” this week - it’s officially due on Tuesday, but it is OK if you turn it in before Friday Dec 2. That will give you more time to make progress. Note: only one member per team needs to fill out the form, but all team members should do the survey to indicate who is doing the form for them.

The Weeks in Vis: The Last Weeks

in Posts
This posting is meant to give you a sense of what is planned for the last weeks of class (post Thanksgiving). Class is dominated by the project: the design exercises are all parts of the project, and there is something due each week. There are some seek-and-finds, and one online discussion left, but we’ll skip those at the end (to make more time for projects). Week 13: Evaluation The topic is important: how do we know that visualizations (or visualization systems or visualization ideas) are good? Read more…

The Week in Vis: Week 12 Color, Projects, Thanksgiving

in Weeks in Vis

It’s Thanksgiving week. The schedule is changed a little. I hope everyone has a good holiday.

This week we have a big topic: color. It seems so central. It seems so basic. But it turns out to be remarkably complex (and important). We can only scratch the surface. But, the amount we’ll do is also constrained by its Thanksgiving week, and the course project is starting (and I want students to focus on that).

Hints for Good Figures (how to do well on DE9)

in Posts
Here are some hints for how to do well on Design Exercise 9: Visualization Hand-Ins - but really, they are advice on how to make good figures generally. These are generated from the experience of grading Design Exercise 5: Aid Data Handin. We discussed most of them in class. Don’t rely on the rationale. Yes, you can argue for why what you are doing are good choices (and you need to do this for the assignment), but a good figure doesn’t need the rationale to explain why it is a good figure.

Grading Information for Aid Data Design Exercises (DE3-DE5)

in Posts
The grading (assessment, not critique) for the “Aid Data Design Exercises” puts together all the scoring information from the 3 assignments (drafts, critiques, and final handins). Short version: your final score is a number between -2 and 2, where 0 is meant to be “expected” (where the mean is). This doesn’t tie neatly to grades. Initial thoughts This turned out to be more complicated than I had thought it was going to be. Read more…

The Week in Vis: Week 11 (Nov 14-18): Design, ATUS Handins

in Weeks in Vis

This week was supposed to be color week. We’ll put that off so we can do things that are timely and relevant to the Design Exercise / Projects: we’ll talk about design, and you’ll read about uncertainty. And in class, we’ll do some brainstorming about projects and help people find partners and choose topics.

Atus Class Questions

in Posts
For Design Exercise 9: Visualization Hand-Ins one of your “stories” must be built from a “class question”. Here are the “class questions” - in that they are for the entire class. Note that for each question, there is a basic question, but then suggestions for more richness/detail/nuance to be layered into an answer/story. You must pick one of these four for the set of visualizations you create for DE9. Note that several of these require doing data joins of the samples with the population/household data set.

The Week in Vis: Week 10 (Nov 7-Nov 11): Perception

in Weeks in Vis

This week we’ll dig into human perception as an important foundation for visualization. We’ll also continue the Time Usage Survey Design Exercise.

This will be a non-standard week because of the Design Exercise: the Tuesday deadline to turn in drafts is strict, and the normal Friday activities will be replaced by doing critiques.
