Basic Usage

Add charming to your Cargo.toml:

toml [dependencies] charming = "0.1.1"

Below is an example of drawing a simple pie chart.

```rs use echarts::{ component::Legend, df, element::ItemStyle, series::{Pie, PieRoseType}, Chart, ImageRenderer };

fn main() { let chart = Chart::new() .legend(Legend::new().top("bottom")) .series( Pie::new() .name("Nightingale Chart") .rosetype(PieRoseType::Radius) .radius(("50", "250")) .center(("50%", "50%")) .itemstyle(ItemStyle::new().border_radius(8)) .data(df![ (40.0, "rose 1"), (38.0, "rose 2"), (32.0, "rose 3"), (30.0, "rose 4"), (28.0, "rose 5"), (26.0, "rose 6"), (22.0, "rose 7"), (18.0, "rose 8"), ]), ) let mut renderer = ImageRenderer::new(1000, 800); renderer.save(&chart, "/tmp/nightingale.svg"); } ```

This code creates the following SVG file:
