Poor attendee involvement can hinder progress and hurt team cohesion. Thus, there is a strong motivation for organizations to better understand what happens in meetings and improve upon their experience. However, analyzing multi-party meetings is a challenging task, as one needs to consider both verbal exchanges and meeting dynamics among speakers. There is currently a lack of support on these unique tasks. In this paper, we present a new visual approach to help analyze multi-party meetings in industry settings: Discussion Flows, a multi-level interactive visualization tool. Its glyph-based overview allows effortless comparison of overall interactions among different meetings, whereas the individual meeting view uses flow diagrams to convey the relative participation of different speakers throughout the meeting agenda in different levels of details. We demonstrate our approach with meeting recordings from an open source dialogue corpora and use them as the benchmark dataset.}, keywords = {Glyphs, Information Visualization}, pubstate = {published}, tppubtype = {conference} } @conference{visactivity2, title = {2nd IEEE VIS Workshop on Data Vis Activities to Facilitate Learning, Reflecting, Discussing and Designing}, author = {Samuel Huron AND Benjamin Bach AND Georgia Panagiotidou AND Mandy Keck AND Jonathan Roberts AND Sheelagh Carpendale}, url = {https://visactivities.github.io/VIS2021_Vis_Activity_Workshop.pdf}, year = {2021}, date = {2021-04-01}, booktitle = {IEEE VIS 2021}, abstract = {This Data Vis Activities workshop is a sequel to our successful workshop at IEEE VIS 2020 [7], focusing on methods and challenges for teaching and engaging with data visualization concepts, knowledge, and practices.

After conducting interviews with product costing experts, we focused on Flow diagrams, which fulfill this basic requirement.

We investigated three visualization techniques applicable to the ribbons of Flow diagrams to convey uncertainty information: Color-code, Gradient, and Margin. Moreover, we designed five visual approaches to show the uncertainty on nodes of Flow diagrams that we evaluated with visualization experts. The approaches add different geometries to the nodes such as triangles, blocks, or forks. The preferred solutions for the nodes was adding forks or filled blocks. With regards to the ribbons, we contribute a user study involving the solution of different product costing tasks using the three different visualizations. Although Gradient was considered an intuitive choice to show uncertainty, it yielded the highest error rates. In contrast, Color-code and Margin were superior depending on the performed task.
