Object.assign(container.style, {

height: `${size.height || 400}px`,
});
document.getElementById('container')!.append(container);

addEventListener('pagehide', () => graph.destroy(), { once: true });
await graph.render();
if (renderPanel) addPanel((gui) => renderPanel(gui, graph));
return container;
}设置 node.type 为 image 以使用图片节点。
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 |
|---|---|---|---|---|
| img | 该属性为 img 的别名 | string | - | |
| src | 图片来源,即图片地址字符串 | string | - | ✓ |
