Description

Why you need it?

Currently, there are two ways to define a StateMachine. One is to use the designer, and the other is to directly write JSON. If users adopt the latter (i.e., do not write JSON through the designer), then it is not supported to import it into the designer because there is no style information (shape, edge positioning). If auto-layout is supported, this scenario will be indirectly supported.

How it could be?

You can extend SagaImporter to add style information.

Research direction
Examine the SagaImporter class (likely in the seata saga module) to understand how it currently imports state machine definitions. The issue suggests that extending this class with auto layout logic will add style information. Review the 14 comments on the issue for any proposed solutions or maintainer guidance. Also check if there is a linked designer frontend repository or relevant files.
