Archived web site from Fall 2021

This was the CS765 Data Visualization Course Web Site for Fall 2021!

The class is now over. This is an archived site. If you are looking for a newer version of the class, check the 2022 web page.

There’s a lot here. You might want to look at Getting Started (Start Here!) to find your way around.

The upper right has a “this week” box that has the immediate events.

If you’re looking for something specific, you can search (box in the upper right) or look at the List of all pages. If you’re browsing, the sidebar has some good destinations.

DC2 Final Dates and Presentations

in Posts

The final handin for Design Challenge 2 is due on Wednesday, December 15. An extension will be granted to teams that volunteer to present their work in class so they can incorporate feedback. Late assignments will be accepted until Sunday, 19th, but may be penalized.

The Week in Vis: Week 14

in Weeks in Vis

We’re getting close to the end. Hopefully, your project is coming along well. Expect all the details for the final expectations soon.

In terms of content… This week is scheduled for two/three very different topics: Scientific Visualization, 3D and Uncertainty Visualization. Scientific Visualization is a whole field unto itself - I can’t teach a Vis course without giving you at least a taste of what its about. 3D comes up a lot in SciVis (and elsewhere). And Uncertainty comes up pretty much everywhere when we work with data - whether we acknowledge it or not.

Dc2 Proposal Codes

in Posts

I tried to provide quick feedback on the proposals - unfortunately, I wasn’t able to spend much time with them, but hopefully I can give something quickly. In order to cram things into Canvas Comments, I coded things. I am showing the codes to everyone - a comment that was given to someone else might apply to you. Indeed, some of the advice applies very generally.

The Week in Vis: Week 13

in Weeks in Vis

Last week was an unusual week because it was Thanksgiving. This week is unnusual because we have leftovers from last week. The topic for discussion is Evaluation - how do we know that a visualization is good?

DC1 Grading

in Posts

This posting will explain how to interpret your DC1 grades. As posted in Canvas, they can be a little hard to read.

Each assignment is ultimately given an 0-100 score (on the standard 90=A, 85=AB, 80=B scale. The University does not give A+s, but we do in class). This grade is only for the final handin - we did not consider other phases.

The final score was determined subjectively - there is no numerical method for combining the ordinal scores in the rubric.

Dc2 Phase1 Feedback

in Posts

I have given people feedback on [Design Challenge 2: A Visualization Project (Hard Vis Problems) (phase-1)](/assigns/dc2/#phase-1) (assuming that you turned it in). It was done quickly and is brief, but hopefully, it can give you some guidance. Things can be discussed in more detail in office hours or after class.

The Week in Vis: Week 12

in Weeks in Vis

We’ve made it to Thanksgiving week - which always seems to mark something in the semester. This is a weird week - both because its the holiday (although, Wednesday is not a holiday, so there is class), and that we’re in the midst of [Design Challenge 2: A Visualization Project (Hard Vis Problems)](/assigns/dc2/).

The topic this week is graphs (as in the “networks” kind). It’s a big topic that we will just touch on. We’ll have a lecture on Monday, and an in-class exercise (with a lecture component) on Wednesday. There is the usual reading and discussion. We’ll allow Seek and Find 12 : Graphs (due Mon, Nov 29) to be after the holiday, and cancel the weekly survey (so there is nothing due on the holiday - you are welcome to do things before the holiday).

We have moved the DC2 deadlines to wednesdays: DC2 Phase 2: Proposal (Design Exercise 9)  (due Wed, Nov 24) and DC2 Phase 3: Formulation (Design Exercise 10).

Discussion Statistics

in Posts

I will soon post some statistics we gathered about discussions to give you a sense of where you are relative to others. While the quantitative metrics are not used directly, they are a good proxy (they correlate well).

We will post the scores (canvas willing) as grading comments in the assignment Discussion Participation Scores (assuming Canvas lets us do this without actually posting a grade).

The initial posting is for the first 7 weeks.

The Week in Vis: Week 11

in Weeks in Vis

This week, two big things happen: we really dig in to Design Challenge 2: A Visualization Project (Hard Vis Problems), and we talk about one of my favorite topics, color.

On Monday, Design Challenge 2: A Visualization Project (Hard Vis Problems) (Phase 1) is due. The main piece is to pick which problem you are going to work on, but the description gives some details of what we expect.

Project proposals are due at the beginning of next week DC2 Phase 2: Proposal (Design Exercise 9)  (Canvas Wed, Nov 24). That’s a major milestone. Hopefully during the week, you’ll make use of all the resources we have (like online discussions and office hours) to come up with good ideas.

And don’t forget to contribute to the DC2 Readings and Brainstorming discussions.

With color, there are many things I’d like to talk about. But instead, we’ll just touch on a few basics. I might try to do a color exercise in class on Wednesday. Or we might try another experiment in group brainstorming for the project.

Design Challenge 2 Released (DC2)

in Posts

Design Challenge 2: A Visualization Project (Hard Vis Problems) has been released. Since it’s in the Assignments section, it might not be as visible, so I am announcing it.

I am purposefully letting it out “early” - not every detail is worked out. I am expecting that student questions will help me figure our which parts need to be better defined.

We will discuss the project in class on Wednesday, so I recommend that you take a look beforehand. If nothing else, get a sense of the three project options so that you can start to decide.
