Examples

Bundled demo

uv run voidmesh-demo

Displays a small force graph using the default controls.

Live changes

uv run python examples/live_changes.py

Opens a non-blocking window, adds nodes over time, and changes the root value and color while the renderer is active.

Systematic tree

uv run python examples/tree_view.py

Displays a project structure in deterministic tree view with custom font and link styling.

Context manager

For short-lived tasks, a canvas can manage its own non-blocking window:

import time
from voidmesh import Canvas

with Canvas() as canvas:
    first = canvas.add_node("First")
    second = canvas.add_node("Second")
    canvas.link(first, second)
    time.sleep(3)

Leaving the block closes the window.
