Developer ahmadawais open-sourced chartli on GitHub, a command-line tool that renders plain numeric text data directly into terminal charts.

The tool supports multiple chart types and rendering modes, including ascii, spark, bars, columns, heatmap, unicode, braille, and svg. Users can run it instantly via npx chartli or install it globally. It also includes an Agent skill installation command for seamless integration into AI agent workflows.
