Blessed Contrib
Build terminal dashboards using ascii/ansi art and javascript
...It extends the Blessed terminal UI framework with visualization widgets designed for ASCII and ANSI environments. Available components include charts, tables, maps, gauges, trees, markdown views, and other dashboard-oriented displays. A grid layout system helps developers arrange multiple widgets into structured terminal interfaces. Applications can remain fully interactive and work naturally over SSH without requiring a browser or graphical desktop. The library supports Linux, macOS, and Windows and is widely useful for monitoring tools, developer dashboards, and terminal-based administration interfaces.
