dr_render

Rich console components and multi-level header tables for CLI rendering.

Why "render"?

This library focuses on rendering data visually in the terminal. Current features include styled tables and console components, with planned extensions for:

• Annotated text rendering (parts of speech, syntax highlighting)
• Colored markup and linguistic visualization
• Other CLI rendering utilities

Installation
