### Create a Simple Line Chart

Source: https://crates.io/crates/embedded-charts/0.3

This example demonstrates how to create a basic line chart using the fluent API provided by the embedded-charts crate. It includes setting line color, width, title, and background color. The chart is then rendered to a display.

```rust
use embedded_charts::prelude::*;
use embedded_graphics::{pixelcolor::Rgb565, prelude::*};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create sample data
    let data = data_points![(0.0, 10.0), (1.0, 20.0), (2.0, 15.0), (3.0, 25.0)];

    // Build chart with fluent API
    let chart = LineChart::builder()
        .line_color(Rgb565::BLUE)
        .line_width(2)
        .with_title("Temperature Over Time")
        .background_color(Rgb565::WHITE)
        .build()?;

    // Render to any embedded-graphics display
    let viewport = Rectangle::new(Point::zero(), Size::new(320, 240));
    chart.draw(&data, chart.config(), viewport, &mut display)?;
    
    Ok(())
}

        Rgb565::YELLOW,
        Rgb565::new(255, 200, 0), // Orange
        PatternType::Checkerboard { size: 4 },
    );
    
    // Apply gradient to chart background
    let chart = BarChart::builder()

### Real-time Data Streaming with LineChart

Source: https://crates.io/crates/embedded-charts/0.3

This Rust code demonstrates real-time data streaming using `SlidingWindowSeries` and `LineChart` from the embedded-charts crate. It simulates data points, pushes them into a sliding window, and renders an animated line chart with smooth transitions. This example is suitable for dynamic visualizations on embedded displays.

```rust
use embedded_charts::prelude::*;

fn streaming_dashboard() -> ChartResult<()> {
    // Create sliding window for continuous data
    let mut stream = SlidingWindowSeries::<Point2D, 100>::new();

    let chart = LineChart::builder()
        .line_color(Rgb565::CSS_LIME_GREEN)
        .line_width(2)
        .fill_area(Rgb565::new(0, 8, 0)) // Semi-transparent fill
        .with_animation(AnimationConfig {
            duration: 500,
            easing: EasingFunction::EaseInOut,
        })
        .build()?;

    // Simulation loop
    for i in 0..1000 {
        // Add new data point
        let timestamp = i as f32 * 0.1;
        let value = 50.0 + 20.0 * (timestamp * 0.5).sin();
        stream.push(Point2D::new(timestamp, value))?;
        
        // Render with smooth animation
        chart.draw(&stream, chart.config(), viewport, &mut display)?;
        
        // Update every 100ms
        std::thread::sleep(std::time::Duration::from_millis(100));

This example shows how to create a smooth curve chart using advanced interpolation techniques like Catmull-Rom. It allows for specifying interpolation type, subdivisions, tension, fill area, and markers for a more visually appealing representation of data.

```rust
use embedded_charts::prelude::*;
use embedded_charts::chart::CurveChart;
use embedded_charts::math::interpolation::InterpolationType;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Temperature data over 24 hours

### Configure Memory for embedded-charts Data Series

Source: https://crates.io/crates/embedded-charts/0.3

This example illustrates memory configuration for `StaticDataSeries` in embedded-charts. It defines different types for varying data point capacities (32, 256, and 1024), suitable for different embedded constraints. This is crucial for managing memory efficiently in resource-limited environments.

```rust
// Ultra-constrained: 32 data points, minimal features
type SmallSeries = StaticDataSeries<Point2D, 32>;

// Standard embedded: 256 data points
type StandardSeries = StaticDataSeries<Point2D, 256>;

// High-capacity: 1024 data points for data logging
type LargeSeries = StaticDataSeries<Point2D, 1024>;

```

It covers buffer configuration, event handling, data pushing, chronological iteration for charting, and calculating moving averages. This implementation is memory-efficient and designed for `no_std` environments.

```rust

// Create ring buffer with 100-point capacity
let mut data_buffer: PointRingBuffer<100> = PointRingBuffer::new();

    track_bounds: true,                       // Auto bounds tracking
    ..Default::default()
};

let mut streaming_buffer: RingBuffer<Point2D, 100> = RingBuffer::with_config(config);

// Set up event handler
streaming_buffer.set_event_handler(|event| match event {
    RingBufferEvent::BufferFull => println!("Buffer is now full!"),
    RingBufferEvent::BoundsChanged => println!("Data bounds have changed"),
    _ => {}
});

// Stream data through the buffer
loop {
    let sensor_value = read_sensor();
    streaming_buffer.push_point(Point2D::new(timestamp, sensor_value))?;
    
    // Use chronological iterator for proper time ordering
    let mut chart_data = StaticDataSeries::<Point2D, 256>::new();
    for point in streaming_buffer.iter_chronological() {
        chart_data.push(*point)?;
    }

        }
        Err(ChartError::InsufficientData) => {
            println!("Need more data points to render chart");
        }
        Err(ChartError::MemoryFull) => {
            println!("Data series capacity exceeded");
        }
        Err(ChartError::InvalidConfiguration) => {
            println!("Chart configuration invalid");
        }
        Err(ChartError::RenderingError) => {
