Introduction: Data visualization is an important part of modern web application development. It helps users understand and analyze data more intuitively. In this article, we will introduce how to get started quickly and build a simple data visualization application using Vue and ECharts4Taro3. The goal of this article is to help readers learn to use these two tools in just one hour.

1. Preparation
   Before starting, please make sure you have Node.js and npm installed. If it is not installed yet, please download and install it first. Then create a new directory, open the command line, enter the directory and run the following command:

   npm install -g @tarojs/cli

2. Create Taro3 project
   Run the following command to create a new Taro3 project:

   taro init myApp
   cd myApp

   After running the above command, you will get a basic Taro3 project structure. After entering the project directory, run the following command to start the development server:

   npm run dev:weapp

   Then use the WeChat developer tools to open the dist directory under the project root directory to preview the effect.

3. Install Vue and ECharts4Taro3
   Next we need to install Vue and ECharts4Taro3. Run the following command:

   npm install vue echarts echarts-for-taro3 --save

4. Add ECharts4Taro3 component
   The method of using ECharts4Taro3 in Taro3 is very simple. Open the src/pages/index/index.jsx file and make the following modifications:

   import React, { Component } from 'react'
   import { View } from '@tarojs/components'
   import TaroECharts from 'echarts-for-taro3'
   
   export default class Index extends Component {
     config = {
    navigationBarTitleText: '数据可视化'
     }
   
     render () {
    const option = {
      title: {
        text: '柱状图示例'
      },
      xAxis: {
        type: 'category',
        data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
      },
      yAxis: {
        type: 'value'
      },
      series: [{
        data: [120, 200, 150, 80, 70, 110, 130],
        type: 'bar'
      }]
    }
   
    return (
      <View className='index'>
        <TaroECharts
          echarts={echarts}
          option={option}
          style={{ height: '300rpx', width: '100%' }}
        />
      </View>
    )
     }
   }

5. Run the project
   After saving the above modifications, return to the command line interface and run the following command to restart Compile the project:

   npm run dev:weapp

   Then refresh the WeChat developer tool to see that the ECharts histogram example has been presented on the page.
