Some other existing options in this space (not all web based) are

- https://pymeasure.readthedocs.io/en/latest/ python Framework for running science experiments, getting hardware to go through a set of steps and plot the output. Includes a GUI.

- https://plotjuggler.io/ for really fast live time series plotting in C++/OpenGL, very fast and quick to chuck data at (just wrap it in JSON and throw over UDP) but lacks any form of input. Ideal for systems running at kHz etc, I've used it to tune motion control systems.

- https://foxglove.dev/ aimed solidly at robotics (think self driving vehicles) renders time series plots, 3D renders and point clouds, log statements etc, and supports inputs too. All written in HTML and you can write extensions for it. Unlike others, it can support a much larger data file on a server and live stream the bit you are currently viewing to your browser. Not as fast for smaller things though.
