b-top (short for bad-top) is a terminal-based, Rust-powered system resource viewer for UNIX-like systems. Inspired by tools like bashtop and htop, b-top provides a visually rich and interactive interface for monitoring CPU, memory, network, and process activity, rendered with smooth animations and intuitive controls.

• Per-Core CPU Usage: Real-time usage display for each CPU core with color-coded indicators.
• CPU Usage Graph: Sparkline graph showing historical average CPU usage.
• Memory Monitoring: Visual gauge showing used vs. total memory in GB.
• Network Stats: Displays RX/TX bytes for interfaces like eth0 and lo.
• Process Table: Sortable list of top processes by CPU, memory, or network usage.
• Smooth Animations: Powered by tachyonfx for subtle UI transitions.
• Keyboard Navigation: Scroll, jump, sort, and switch interfaces with intuitive keybindings.

• ratatui – Terminal UI rendering
• sysinfo – System information
• crossterm – Terminal input handling
• tachyonfx – Animation effects

Thanks to ratatui and TachyonFX repositories for maintaining their projects for for the UI animations.

Because it's my first Rust project and it's undeniably terrible.
