1//! Dashboard layout system for composing multiple charts
2//!
3//! This module provides a flexible layout system for arranging multiple charts
4//! on a single display, perfect for creating comprehensive dashboards in embedded
5//! systems.
6//!
7//! ## Example
8//!
9//! ```rust,no_run
10//! use embedded_charts::dashboard::{SimpleDashboard, GridPosition};
11//! use embedded_graphics::prelude::*;
12//! use embedded_graphics::pixelcolor::Rgb565;
13//! use embedded_graphics::primitives::Rectangle;
14//!
15//! // Create a 2x2 dashboard
16//! let dashboard = SimpleDashboard::new(2, 2, 10);
17//! let total_viewport = Rectangle::new(Point::new(0, 0), Size::new(400, 300));
18//!
19//! // Get viewport for top-left position
20//! let chart1_viewport = dashboard.get_viewport(
21//!     GridPosition::new(0, 0),
22//!     total_viewport
23//! );
24//!
25//! // Draw your chart in this viewport
26//! // chart.draw(data, config, chart1_viewport, &mut display)?;
27//! ```
