## What it is
A lightweight, dependency-free library for rendering ASCII line charts in the console, available for NodeJS, browsers, and Python (asciichartpy). It plots numeric series as nice-looking text charts with configurable height, offset, and label formatting.

## Use cases
- plot a data series as an ascii chart in the terminal
- visualize sensor or log data in console without a GUI
- render line charts in the browser console
- add quick text-based charts to CLI tools
- plot time series in a Python script as text
- debug numeric data with a quick terminal chart

## When to choose
- you need zero-dependency text charts in a terminal or console
- you want to visualize data where GUIs or images aren't available (SSH, logs, REPL)
- you need a tiny charting utility for NodeJS, browser, or Python

## When to avoid
- you need interactive, high-resolution, or graphical charts
- you need bar charts, pie charts, or chart types beyond line charts
- you need charts for reports or web dashboards with rich visuals

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, charts, cli
- domain: data-visualization, developer-tools
- platform: browser, cli, cross-platform, python
