Echarts如何绘制四维数据散点图

Question

大家好，我是Echarts新手！最近想使用Echarts实现四维数据可视化的功能，查询官网示例，相似的样例是3D散点图，但是缺少数据输入的部分。我现在的数据是以文件存储的，大概有40000+组数据，请问如何将数据导入echarts并且绘制出与样例相似的图像？

数据形式大概为：

-1.45,-1.95,-2.05,0.0909931
-1.45,-1.95,-1.85,0.101601
-1.45,-1.35,-0.85,0.274918

数据输入不就是你自己去请求文件，得到数据，然后把数据处理成scatter3D需要的数据格式，scatter3D需要的数据格式可以看https://echarts.apache.org/zh...

主要就是一个数组，代表散点集合，数组每个元素代表一个点，这个元素可以是一个数组，也可以是一个对象格式，拿你发的案例来说，就是一个数组，分为四项，正好对应你的数据[x, y, z, value]
