Excited to share this: I have just released Wizkers.io, a complete data logging and visualization framework.
For BeagleBone/BeagleBoard users, this means a super easy to install system (pure NodeJS) that can give a not only a web user interface and local data visualization layer to your projects, but also take care of all the logging and connections to backend IoT services for data upload. And it runs great on a BBB.
Oh yeah, and it is Open Source, of course.
