# Chart plotter
1. Read the column the user named and drop any row that is not a number.
2. Choose the axis range from the data rather than from zero, unless the user says
otherwise.
3. Hand the numbers to [`scripts/plot.py`](scripts/plot.py), which saves the PNG
beside the data file.
4. Print the path of the PNG.
