数据可视化 期末 题库 数据可视化分析课程

安装环境:

1.tomcat安装和配置教程:https://jingyan.baidu.com/article/870c6fc33e62bcb03fe4be90.html

2.任意编译器(甚至可以使用TXT文件),本博客推荐使用pycharm以及Visual Studio;

3.安装完成tomcat之后,在/webapps目录文件下创建一个新文件夹,本文创建的是vis2021文件夹

4.在之后的调试过程中,即通过使用浏览器输入127.0.0.1:8080/vis2021/文件名.html来进行实时的预览,另外可以通过右键浏览器检查代码。(通过课程学习,也明白了每完成一部分内容一定要进行一个实时的预览,检查对应模块是否报错)
