圆形组合 Circle

概述

圆形组合以圆形边界包裹子节点或子组合，适合表示平等或非层级化的群组关系。

适用场景：

适合表示无明确层级关系的节点群组，圆形组合能体现成员的平等性，如社交网络中的用户群体、分散式团队结构（突出协作性）。

import { Graph } from '@antv/g6';
import GUI from 'lil-gui';

export function addPanel(renderPanel: (gui: GUI) => void) {
  const gui = new GUI({ container: document.body });
  gui.title('Control');
  Object.assign(gui.domElement.style, { position: 'absolute', top: '0', right: '0', zIndex: '10' });
  renderPanel(gui);
  addEventListener('pagehide', () => gui.destroy(), { once: true });
}

export async function createGraph(
  options: ConstructorParameters<typeof Graph>[0],
  size: { width?: number; height?: number } = {},
  renderPanel?: (gui: GUI, graph: Graph) => void,
) {
  const container = document.createElement('div');
  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 combo.type 为 circle 以使用圆形组合。

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 BaseCombo

示例

以下示例为兴趣小组人员分布：

import { Graph } from '@antv/g6';

const graph = new Graph({
  container: 'container',
  width: 600,
  height: 600,
  autoFit: 'center',
  data: {
    nodes: [
      { id: 'node1', combo: 'combo2', style: { x: 150, y: 150 } },
      { id: 'node2', combo: 'combo2', style: { x: 200, y: 150 } },
      { id: 'node3', combo: 'combo3', style: { x: 300, y: 150 } },
      { id: 'node4', combo: 'combo3', style: { x: 350, y: 150 } },
      { id: 'node5', combo: 'combo4', style: { x: 230, y: 300 } },
      { id: 'node6', combo: 'combo4', style: { x: 280, y: 300 } },
    ],
    combos: [
      { id: 'combo1', style: { labelText: '兴趣小组' } },
      { id: 'combo2', combo: 'combo1', style: { labelText: '书法' } },
      { id: 'combo3', combo: 'combo1', style: { labelText: '影视' } },
      { id: 'combo4', combo: 'combo1', style: { labelText: '游戏' } },
    ],
  },
  node: {
    style: {
      labelText: (d) => d.id,
    },
  },
  behaviors: ['drag-element', 'collapse-expand'],
  animation: true,
});

}
