Struct GraphRenderer 

pub struct GraphRenderer {
    pub canvas_width: u32,
    pub canvas_height: u32,
}

A simple canvas-based renderer that produces ASCII art.

Fields

canvas_width: u32

Canvas width in character columns.

canvas_height: u32

Canvas height in character rows.

Implementations

impl GraphRenderer

pub fn new(canvas_width: u32, canvas_height: u32) -> Self

Creates a new renderer with the given canvas dimensions.

pub fn render_ascii( &self, layout: &GraphLayout, nodes: &[(u64, String)], ) -> String

Renders the layout as an ASCII art string.

Each node is represented as [name] placed at its grid position (scaled to fit the canvas). The returned string contains canvas_height lines separated by '\n'.
