使用jsdom、highcharts创建Treemap服务器端

使用jsdom和highcharts创建Treemap服务器端，可以通过以下步骤实现：

安装依赖：首先，确保已经安装了Node.js和npm。然后，在命令行中进入项目目录，运行以下命令安装所需的依赖包：

npm install jsdom highcharts

创建服务器端脚本：在项目目录下创建一个名为server.js的文件，并在文件中编写以下代码：

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const Highcharts = require("highcharts");
require("highcharts/modules/treemap")(Highcharts);

// 创建Treemap图表
function createTreemapChart() {
  const dom = new JSDOM(`<!DOCTYPE html><html><body><div id="container"></div></body></html>`);
  const window = dom.window;
  global.window = window;
  global.document = window.document;

  const chartOptions = {
    series: [{
      type: "treemap",
      layoutAlgorithm: 'squarified',
      data: [{
        name: 'A',
        value: 6,
        colorValue: 1
      }, {
        name: 'B',
        value: 6,
        colorValue: 2
      }, {
        name: 'C',
        value: 4,
        colorValue: 3
      }]
    }],
    title: {
      text: "Treemap Chart"
    }
  };

  const chart = Highcharts.chart("container", chartOptions);
  const svg = chart.container.innerHTML;

  return svg;
}

// 创建HTTP服务器并返回Treemap图表
const http = require("http");
const server = http.createServer((req, res) => {
  const svg = createTreemapChart();
  res.writeHead(200, { "Content-Type": "image/svg+xml" });
  res.end(svg);
});

const port = 3000;
server.listen(port, () => {
  console.log(`Server running at http://localhost:${port}/`);
});
