Ervy is a small JavaScript library for rendering ASCII charts (bar, pie, bullet, donut, gauge, scatter) directly in the terminal. It provides a simple API for colored terminal output and can also be used as a CLI tool.
Use cases
- render bar charts in the terminal
- draw pie and donut charts as ASCII art
- visualize data in a CLI script
- add colored terminal output to Node.js apps
- display gauge or bullet charts in console dashboards
When to choose
- you need lightweight, dependency-free ASCII charts in a Node.js terminal app
- you want quick console-based data visualization without a GUI
- you enjoy terminal/ASCII aesthetics for CLI output
When to avoid
- you need interactive or high-resolution graphical charts
- you need a web-based charting solution
- you require a library with frequent updates or extensive chart types
