五角形节点 Star

概述

星形是一个多角几何形状，具有突出的角。

适用场景：

用于表示重要节点、特殊标记或装饰性元素。
适合表示流程图、网络图或拓扑图。
常用于流程图、网络图、拓扑图等。

  Object.assign(container.style, {
    width: '100%',
    maxWidth: `${size.width || 600}px`,
    height: `${size.height || 400}px`,
  });
  document.getElementById('container')!.append(container);
  const graph = new Graph({ ...size, ...options, width: container.clientWidth, container, autoResize: true });
  addEventListener('pagehide', () => graph.destroy(), { once: true });
  await graph.render();
  if (renderPanel) addPanel((gui) => renderPanel(gui, graph));
  return container;
}

设置 node.type 为 star 以使用星形节点。

样式配置

如果元素有其特定的属性，我们将在下面列出。对于所有的通用样式属性，见 BaseNode

属性	描述	类型	默认值	必选
innerR	内半径，是指从星形中心到内顶点的距离	number	默认为外半径的 3/8
