netrunner_cli 0.7.3

//! # Statistics Dashboard Example
//!
//! This example demonstrates the interactive statistics TUI powered by `tui-piechart`.
//! It seeds the history database with 20 realistic fake speed-test entries spanning
//! the last 30 days, so the dashboard looks great even if you have never run a real
//! test, then immediately launches the full-screen statistics viewer.
//!
//! ## Usage
//!
//! ```sh
//! cargo run --example statistics_dashboard
//! ```
//!
//! ## Features demonstrated
//!
//! - Seeding [`HistoryStorage`] with varied, realistic [`SpeedTestResult`] data
//! - Mixed [`ConnectionQuality`] ratings (Excellent → Failed) for a rich pie-chart
//! - Four European server locations: Frankfurt, Amsterdam, London, Paris
//! - Full-screen interactive TUI with pie-charts and a scrollable results table
//!
//! ## TUI controls
//!
//! | Key               | Action                                      |
//! |-------------------|---------------------------------------------|
//! | `Tab` / `→`       | Cycle to the **next** chart panel           |
//! | `←`               | Cycle to the **previous** chart panel       |
//! | `↑` / `k`         | Scroll the results table **up**             |
//! | `↓` / `j`         | Scroll the results table **down**           |
//! | `q` / `Esc`       | **Quit** the TUI and return to the terminal |
//!
//! ## Charts included
//!
//! 1. **Download speed** distribution (pie-chart, bucketed by Mbps range)
//! 2. **Upload speed** distribution (pie-chart, bucketed by Mbps range)
//! 3. **Ping / latency** distribution (pie-chart, bucketed by ms range)
//! 4. **Connection quality** breakdown (pie-chart, one slice per quality tier)
//!
//! A summary panel on the right shows aggregate statistics (avg / max / min for
//! download, upload and ping), and the bottom half of the screen lists every
//! result in a scrollable table.
//!
//! ## Notes
//!
//! - The seeded entries are written into the **same** persistent history database
//!   used by the `netrunner` binary (`~/.netrunner_cli/history.db`).  Running the
//!   example multiple times will accumulate more entries; this is harmless — the
//!   database enforces a 30-day rolling retention window automatically.
//! - No network access is required to run this example.
