Visualizing the commit history of the Python scripting language project.

This visualization, called code_swarm, shows the history of commits in a software project. A commit happens when a developer makes changes to the code or documents and transfers them into the central project repository. Both developers and files are represented as moving elements. When a developer commits a file, it lights up and flies towards that developer. Files are colored according to their purpose, such as whether they are source code or a document. If files or developers have not been active for a while, they will fade away. A histogram at the bottom keeps a reminder of what has come before. [1]

Michael Ogawa’s research focus is in software visualization. He is interested in bringing to light the efforts of software developers: How they work together on projects effectively to create some of the largest and most complex systems in the world. Complementary to that goal, he is also interested in designing visually appealing applications that capture an emotional aspect not seen in charts and graphs.[2]
