## Example

### Built-in Triangle Node Effect

```js | ob { inject: true }
import { Graph, iconfont } from '@antv/g6';

const style = document.createElement('style');
style.innerHTML = `@import url('${iconfont.css}');`;
document.head.appendChild(style);

const data = {
  nodes: [
    { id: 'default' },
    { id: 'halo' },
    { id: 'badges' },
    { id: 'ports' },
    {
      id: 'active',
      states: ['active'],
    },
    {
      id: 'selected',
      states: ['selected'],
    },
    {
      id: 'highlight',
      states: ['highlight'],
    },
    {
      id: 'inactive',
      states: ['inactive'],
    },
    {
      id: 'disabled',
      states: ['disabled'],
    },
  ],
};

const graph = new Graph({
  container: 'container',
  data,
  node: {

    style: {

      direction: (d) => (d.id === 'ports' ? 'left' : undefined),

      badgePadding: [1, 4],
      portR: 3,
      ports: (d) =>
        d.id === 'ports'
          ? [{ placement: 'left' }, { placement: 'right' }, { placement: 'top' }, { placement: 'bottom' }]
          : [],
    },
  },
  layout: {
    type: 'grid',
  },
});

graph.render();
