How to use it well

Write a short script that reads a sample data file, labels axes, and selects an output format. Keep transformations explicit and inspect the exported result at its intended size. Reuse scripts for related datasets, but check missing values and column changes so an automated batch does not silently plot the wrong quantity.

This is best suited to automated plots from scientific data files. Before committing a larger project, account for these trade-offs: requires learning plotting commands; modified redistribution follows a custom license.
