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.

Contributor guide

Research direction
Study the SagaImporter class and understand how style information is structured. Look at existing layout algorithms (e.g., graphviz) and determine how to auto generate positions for nodes and edges based on the state machine transitions. Investigate if there is any existing auto layout code in the project.
