GitHut [githut.info], developed by Microsoft data visualization designer Carlo Zapponi, is an interactive small multiples visualization revealing the complexity of the wide range of programming languages used across the repositories hosted on GitHub.
GitHub is a web-based repository service which offers the distributed revision control and source code management (SCM) functionality of Git, enjoying more than 3 million users.
Accordingly, by representing the distribution and frequency of programming languages, one can observe the continuous quest for better ways to solve problems, to facilitate collaboration between people and to reuse the effort of others.
Programming languages are ranked by various parameters, ranging from the number of active repositories to new pushes, forks or issues. The data can be filtered over discrete moments in time, while evolutions can be explored by a collection of timelines.
