BitQuery is a GitHub API driven and D3 based search engine for open source repositories.

BitQuery pursues three main objectives:

• (I) Query the repository metadata via text mining and clustering methods, thus providing an automatic categorization system for software developers
• (II) Establish visual data exploration and topic driven navigation of GitHub repositories for more transparency in source code management
• (III) Promote discoverability and technology transfer for data science and project teams

The BitQuery architecture consists of three abstraction layers, following the visual analytics approach (D. Keim, 2008):

• GitHub API based parser layer (Data Management)
• Smart Data layer (Analysis)
• D3-3D Visu layer, or BitQuery Visual Analytics application (VA-App) (Visualization)

Visual Analytics layouts of BitQuery include:

• Special edition - Visual data mining of open source libraries, package networks and other well-documented data collections. The following metadata types are supported: JSON, YAML, DCF and Markdown.
• CRAN edition - Explore and query the R universe, a comprehensive collection of R packages on GitHub including both the official CRAN packages and the developer versions.
• GitHub edition - Explore and query GitHub organizations. At present, there are more than one million organizations on GitHub, among them Amazon Web Services, Microsoft Azure, Google Cloud Platform and many more.
• HCA Multilevel Edition (Beta (but working) version for various CRAN and Organizations data sets)
• Data Projector Edition (experimental Three.js Visualization)
