Add fewlines

[jserv]

fewlines is a Python/C++ library for creating compact, text-based visualizations in command-line outputs and log files. It generates minimalist histograms, time series charts, and dashboards using only a few lines of text. Ideal for quick data representation in terminals or for logging multi-chart dashboards.

Is this an output formatter or interactive application? I try to keep formatters off the list because there's a lot of them and not something I consider to be a "user interface"

I believe fewlines does the former, and I agree with your concern about focusing on interactive ones.
