 Terminal Plotter is script that reads numeric data from a file (by default `data.txt`) and displays it as a live-updating plot in the terminal using [plotext](https://pypi.org/project/plotext/). The plot shows a moving time window (TW) of the data, and you can interactively adjust the window's size and position using keyboard controls.
