17 | | -## Explanation |
18 | | - |
19 | | -#### Start Node |
20 | | -A graph(json) only have one start node, this will mapping to LangGraph START |
21 | | - |
22 | | - |
23 | | - |
24 | | -#### Step Node |
25 | | -Step Node will mapping to LangGraph add_node, you can drag edge from left node(right port) to right node(left port) |

29 | | -if you drag two node toward to each other, can create cycle. |

31 | | -#### Step Node with tool |
32 | | -Step node fill tool will call function, the tool definition need a tool node |
33 | | - |
34 | | - |
35 | | - |
36 | | -#### Tool Node |
37 | | -Tool node need write real python function code, and need `@tool` decorator like LangChain Custom Tools |
38 | | - |
39 | | - |
40 | | - |
41 | | -#### Contition Node |
42 | | -CONDITION node will mapping to LangGraph conditional_edge |
43 | | - |
44 | | -* green edge is true case path |
45 | | -* red edge is false case path |
