Visualizations of JMRI Development Activity
The JMRI CodeFlower provides a dynamic
view of the structure of whole GitHub source code repository. It shows the relative size of
the code in each file and the structure in which the files are stored.
You can see graphs of the JMRI developer activity on the GitHub project page for the
main code repository and
the website.
More detailed metrics are available on the JMRI
OpenHub pages on contributors and commits.
Dennis Miller created a Code
Swarm of JMRI development that represents activity from inception to January 2009. A Code
Swarm is a fascinating and dynamic visual representation of change as developers come and go
and make changes to the files that make up a project. More information is available on the
Code Swarm page.
