Как создать круговую диаграмму при помощи canvas?

const { createCanvas, loadImage } = require('canvas')
const canvas = createCanvas(200, 200)
const ctx = canvas.getContext('2d')

const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const MiniCssExtractPlugin = require("mini-css-extract-plugin")
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

const fs = require('fs')

function generateHtmlPlugins(templateDir) {
  const templateFiles = fs.readdirSync(path.resolve(__dirname, templateDir));
  return templateFiles.map(item => {
    const parts = item.split('.');
    const name = parts[0];
    const extension = parts[1];
    return new HtmlWebpackPlugin({
      filename: `${name}.html`,
      template: path.resolve(__dirname, `${templateDir}/${name}.${extension}`),
      inject: false,
    })
  })
}

const htmlPlugins = generateHtmlPlugins('./src/html/views')
