I've gotten a bit behind with posting highlights from my visualization course projects, so this is a catch-up post. Since 2019, I've been teaching two visualization courses, CS 625 Data Visualization and CS 725/825 Information Visualization and Data Analytics. In this post, I'll cover CS 725/825 from Spring 2021 , CS 625 from Fall 2021 , and CS 725/825 from Spring 2022 . (Previous semester's posts are available via the VisProjects label on the blog.) CS 725/825 - Spring 2021 In 2019, I was asked to develop a 600-level data visualization course to be part of the core requirements for ODU's MS in Data Science and Analytics program . Since this new course could cover the basics of data visualization theory, I was able to adapt my existing CS 725/825 Information Visualization course to include more advanced topics, which also allowed it to serve as an elective in the Artificial Intelligence and Machine Learning concentration of the new MS program. With these changes,...

  https://xkcd.com/2537/ Seven courses from the Web Science and Digital Libraries ( WS-DL ) Group will be offered in Spring 2022.  Because of the continuing Covid-19 situation , the classes will be a mixture of on-line, f2f, and hybrid.  Be sure to check with the instructor and/or the class schedule to verify how the class will be conducted.  Also keep in mind that the f2f classes might go on-line during the semester.   CS 495/595 Web Security , Dr. Michael L. Nelson , Mondays, 7:10-9:50pm.  Topics : HTTP, Cross-Site Request Forgery, Same Origin Policy, Cross-Site Scripting (XSS), Fingerprinting, Denial-of-service, Phishing.    CS 620 Intro to Data Science & Analytics , Dr. Sampath Jayarathna , Web PLE.

I’ve been meaning to write this for a couple years. Now seems an especially appropriate time for it. In particular, a hybrid course may be an option if staggered in-class attendance is something that will be implemented in the Fall. My first hybrid class began as an in-class "flipped" model.  So first, I'll talk about how I implemented the flipped mode and then I'll discuss how I handled the hybrid (in-class and online) aspects the following year. My definition of a "flipped" class (see https://en.wikipedia.org/wiki/Flipped_classroom , http://flippedclass.com/whyteachersmattermoreinflippedclassroom/ , http://facultyinnovate.utexas.edu/teaching/flipping-a-class ) is one in which students actually do the reading before the class meeting, and the class meeting time is spent discussing the material with students ( not lecturing) and doing in-class activities. There can be several benefits to this, including that class time is changed from content delivery to ac...

" Both arXiv and archive.org are invaluable projects which, if they didn't exist, we would dismiss as obviously ridiculous and unworkable." A record five WS-DL classes are offered for Spring 2019: CS 432/532 Web Science is taught by Alexander Nwala , Thursdays 4:20-7:00pm.  This class explores web phenomena with a variety of data science tools such as Python, R, D3, ML, and IR.  CS 725/825 Information Visualization is taught by Dr. Michele C. Weigle , Wednesdays 9:30am-12:15pm. This class will explore the background and tools needed to develop effective visualizations through analyzing existing visualizations and visualization problems. CS 734/834 Information Retrieval is taught by Dr. Jian Wu , Tuesdays & Thursdays, 9:30-10:45am.  This class will explore the theory and engineering of information retrieval in the context of developing web-based search engines. CS 795/895 Human-Computer Interaction (HCI) is taught by Dr. Sampath Jayarathna , Tuesdays...

(Previous semester highlights posts: Spring 2017 , Spring 2016 , Spring 2015 , Spring/Fall 2013 , Fall 2012 , Fall 2011 ) Here are a few projects that I'd like to highlight from Fall 2017. (All class projects are listed in my InfoVis Gallery .)  All of the projects were implemented using the D3.js library. World Leader Interactions on Social Media (Twitter)  Created by Grant Atkins This project (available at http://www.cs.odu.edu/~gatkins/world-leader-vis/app/ ) provides an interactive dashboard to visualize ways Twitter list data can be used and represented. This visualization uses the World Leaders list on Twitter , with the addition of a few world leaders not on the list, to derive information and visualize shared information among these users. The goal of this visualization is to show shared term usage among world leaders, see which times tweets are more likely to be sent out, the sentiment of the users, and the decay of data allocated in a static decreasin...

This may sound familiar , but yet again I'm way behind in posting about my previous offerings of CS 725/825 Information Visualization. (Previous semester highlights posts: Spring 2016 , Spring 2015 , Spring/Fall 2013 , Fall 2012 , Fall 2011 ) Here are a few projects that I'd like to highlight from Spring 2017. (All class projects are listed in my InfoVis Gallery .  This semester has its own page because there were 19(!) projects.)  All of the projects were implemented using the D3.js library. Because the Spring 2017 semester began with President Donald Trump's Travel Ban ( EO 13769 ) and we have a large international graduate student population, students were understandably interested in US immigration and refugee data.  The first two projects here focus on that.  In addition, one project looked at sentiment about the US Presidential candidates on social media on Election Day. The last two projects that I'll highlight are focused on the lighter topic of ...
