+参考：[Mermaid 参考](https://docs.min2k.com/zh/mermaid/syntax)
+Obsidian支持 Mermaid 图表，思维导图（但是很丑）：
+```mermaid
+mindmap
+	A["`**根节点** 支持一定的Markdown 🤓`"] 
+		B["子节点"] 
+		C["子节点"]
+			D["子节点的子节点"]
+			E["子节点的子节点"]
+			F["子节点的子节点"]
+```
+时序图：
+```mermaid
+sequenceDiagram
+    Alice->>John: Hello John, how are you?
+    John-->>Alice: Great!
+    Alice-)John: See you later!
+```

+```
+
+饼干图
+```mermaid
+block-beta
+  columns 3
+  a["饼干1"] b["饼干2"]:2 c["饼干3"]:2 d["饼干4"]
+```
+何意味：
+```mermaid
+stateDiagram
+    [*] --> Still
+    Still --> [*]
+
+    Still --> Moving
+    Moving --> Still
+    Moving --> Crash
+    Crash --> [*]
+```
+目前正在研究如何使其变得更美观。
