1/// An enumeration representing different fill modes for area traces in plots.
2///
3/// The `Fill` enum specifies how the area under or between traces should be filled
4/// in plots like scatter plots, line plots, and polar scatter plots.
5///
6/// # Example
7///
8/// ```rust
9/// use plotlars::{Fill, Mode, Plot, Rgb, ScatterPolar, Text};
10/// use polars::prelude::*;
11///
12/// let angles: Vec<f64> = (0..=360).step_by(10).map(|x| x as f64).collect();
13/// let radii: Vec<f64> = angles.iter()
14///     .map(|&angle| 5.0 + 3.0 * (angle * std::f64::consts::PI / 180.0).sin())
15///     .collect();
16///
17/// let dataset = DataFrame::new(angles.len(), vec![
18///     Column::new("angle".into(), angles),
19///     Column::new("radius".into(), radii),
20/// ])
21/// .unwrap();
22///
23/// ScatterPolar::builder()
24///     .data(&dataset)
25///     .theta("angle")
26///     .r("radius")
27///     .mode(Mode::Lines)
28///     .fill(Fill::ToSelf)  // Fill the area enclosed by the trace
29///     .color(Rgb(135, 206, 250))
30///     .opacity(0.6)
31///     .plot_title(Text::from("Filled Polar Area Chart"))
32///     .build()
33///     .plot();
34/// ```
