It supports realtime plotting (Matplotlib), serial communication (Pyserial), and socket connections out of the box. It uses a declarative data flow syntax, which means you specify how the pipeline should behave and then you run the pipeline.For example, you can build a real time plot of ...

As Real Python’s own Dan Bader has advised, taking the time to dissect code rather than resorting to the Stack Overflow “copy pasta” solution tends to be a smarter long-term solution. Sticking to the object-oriented approach can save hours of frustration when you want to take a plot ...
