如何基于BaklavaJS流程图在JavaScript中生成代码

我正在使用BaklavaJS库创建流程图，自定义了SwitchNode、SayTextNode等节点。现有如下示例流程图：

需要生成以下Python代码：

print("hi")
print("How i can help")

input = input()
if input == 1:
    print("one")

if input == 2:
    print("two")

if input == 3:
    print("three")

该库会生成包含所有节点及连接关系的JSON对象，示例JSON如下：

    {
      "type": "StartNode",
      "id": "node_16655291011630",
