+# 太极图形课S1-标题部分
+这个作业未来或将是你的开源项目，标题的内容可以来自作业中的核心关键词，让读者一眼看出你所完成的工作/做出的好玩demo
+
+如果暂时未想好，起名时可以参考“太极图形课S1-xxx作业”
+
+如下是作业（项目）展开说明的方法，可以帮大家理清思路，并且也对读者非常友好，请小伙伴们多多参考哦
+
+## 背景简介
+这里可以简要描述作业（项目）的基本背景情况，它源自哪里？能够有效解决哪些问题？可以尽情列举它的亮点哦
+
+## 成功效果展示
+这里可以展示这份作业（项目）run起来后的可视化效果，可以让其他人更直观感受到你的工作
+
+![fractal demo](./data/fractal.jpg)
+## 整体结构（Optional）
+脉络清晰的结构能完整展示你的设计思想，以及实现方式，方便读者快读代入，建议可以在repo的目录中包含如下内容：
+这个部分希望大家可以大作业中加入，小作业中可以选择性加入（如果不加也是OK的）
