 State changes are emitted by the `onNodesChange` or `onEdgesChange` events, which will provide an array of changes that
 have been triggered.
 To take control of state changes you can implement your own state update handlers or use the state helper functions that
 come with the library to mix it up.

 ## Access State in Options API
 
 `useVueFlow` was designed to be used in the composition API, __but__ it is still possible to use it in the options API.

 will create a new state instance
 when mounted.
