Supplementary Data for: Collaborative Software Visualization for Program Comprehension Introduction This package contains supplementary data for our submission. Included are The evaluation's raw results Video recordings of all participants and all modes (compressed) Instructions for replication that also include necessary software such as LimeSurvey or ExplorViz Jupyter Notebooks that visualize the evaluation's results Further information such as a compiled list of feature requests that particpants' mentioned in the open-ended questions General README.md files are included in different folders and include further information. This package contains different software packages, e.g., the version of ExplorViz which was used in the study, that are packaged as Docker Images. We provide different Docker Compose that can be used to start a software package. To start a Docker Compose file and its referenced software, navigate with your command line to the folder that contains the corresponding file and enter docker compose up -d. The Docker Compose file includes potential host ports that are being redirected to potential ports inside of the Docker container, therefore the executed software. For example, LimeSurvey is configured to use the host's port 8082. As a result, it should be accessible under http://localhost:8082. The study was conducted in German language. Therefore, the questionnaire also poses questions that are written in German. We have translated the quantitative and qualitative results of our user study into English. Despite being compressed, the size of the video recordings is 37 GB. As a result, we outsourced all recordings so that they are accessible under https://zenodo.org/record/6795918.
