Pattern-Switchable Tape Lines
This example replaces standard relation-graph edges with slot-rendered ribbon paths on a fixed tree layout. It combines a root CSS fill variable, reusable SVG pattern defs, click-preserving custom line rendering, shared canvas controls, and screenshot export so the same ribbons can switch between solid and animated fills at runtime.
Switchable Pattern-Filled Ribbon Lines on a Tree Graph
What This Example Builds
This example builds a small tree viewer in which every relation is rendered as a filled ribbon instead of a standard stroked edge. The canvas uses a dark grid background, magenta rectangular nodes, and a floating helper window that lets the user restyle all visible ribbons at runtime.
Users can switch the line fill between a plain translucent color and multiple SVG pattern presets, including animated stripes,
