Project topics have been identified across sectors, technologies and research fields. This mapping process was iterated multiple times as part of the analysis and will continue to evolve as niches develop and emerge. While it may be difficult to compare the scope of the topics directly, the relative size and complexity allows us to identify neglected, vibrant, and emerging areas.
The following scatter plot provides an overview of all projects studied within their respective topics. The size of the circles is proportional to the relative scale of the projects, based on total commits and contributions. The colour bar shows the Development Distribution Score (DDS) as a measure of the distribution of work among the individual developers. A high value indicates a high distribution of work and, thus, a strong developer community. More details about this can be found in chapter Development Distribution Score.
