### Example

``` rust

pub fn example_graph(ctx: &mut Context, links: &mut Vec<(usize, usize)>, ui: &mut Ui) {

    // add nodes with attributes

    let nodes = vec![

        NodeConstructor::new(0, Default::default())

            .with_title(|ui| ui.label("Example Node A"))

            .with_input_attribute(0, Default::default(), |ui| ui.label("Input"))

            .with_static_attribute(1, |ui| ui.label("Can't Connect to Me"))

            .with_output_attribute(2, Default::default(), |ui| ui.label("Output")),

        NodeConstructor::new(1, Default::default())

            .with_title(|ui| ui.label("Example Node B"))

            .with_static_attribute(3, |ui| ui.label("Can't Connect to Me"))

            .with_output_attribute(4, Default::default(), |ui| ui.label("Output"))

            .with_input_attribute(5, Default::default(), |ui| ui.label("Input"))

    ];

    // add them to the ui

    ctx.show(

        nodes,

        links.iter().enumerate().map(|(i, (start, end))| (i, *start, *end, LinkArgs::default())),

        ui

    );

    

    // remove destroyed links

    if let Some(idx) = ctx.link_destroyed() {

        links.remove(idx);

    }

    // add created links

    if let Some((start, end, _)) = ctx.link_created() {

        links.push((start, end))

    }

}
