piadda

piadda is another data dashboard attempt

The main goal is allow visualizing data from ROS2 nodes, in mobile devices or client machines that do not have ROS2 local installation.

The piadda serves a web-application that runs in a device that should have access to ROS2 nodes.

The data could be visualized connecting to device's IP from a web browser.

The client-side do not need ROS2 local installation, because piadda provides an abstraction layer using django-channels (websockets) in order to streaming data from ros2-end-device to client-browser.

The piadda is similar to PlotJuggler but providing a web interface to data visualization.
