@antv/vis-predict-engine 可视化预测引擎

图布局预测

目前布局预测的模型由本引擎内置，支持force/radial/concentric/circular的四布局分类，后续将支持更多布局分类。

使用方法

import { GraphLayoutPredict } from '@antv/vis-predict-engine';
const { predictLayout, confidence } = await GraphLayoutPredict.predict(data, expectLayout, showLog);

入参：

• data: 图数据（格式见使用示例），必传;
• expectLayout: 期望布局('force' | 'radial' | 'concentric' | 'circular' )，如无期望布局可传undefined;
• showLog: 是否需要是输出日志（布尔）, 传false或不传则不输出日志； 返回：
• predictLayout: 预测布局, string;
• confidence: 置信度，number。

使用示例

import G6 from "@antv/g6";
import { GraphLayoutPredict } from "@antv/vis-predict-engine";

const data = {
  nodes: [
    {
      id: "node-0",
      label: "0"
    },

      label: "1"
    },
    {
      id: "node-2",
      label: "2"
    },
    {
      id: "node-3",
      label: "3"
    },
    {
      id: "node-4",
      label: "4"

    },
