Pie Charts

The following imports have been used to produce the plots below:

#![allow(unused)]
fn main() {
use plotly::common::{Domain, Font, HoverInfo, Orientation};
use plotly::layout::{
        Annotation, Layout, LayoutGrid},
use plotly::layout::Layout;
use plotly::{Pie, Plot};
}

The to_inline_html method is used to produce the html plot displayed in this page.
