@sidarthv96 Hey Sid! Our team (@nghtlinh @megantriplett @udvale) has been working on issue #6262. We added an alert dialog to let users know that the valid task score range for the journey diagram is 1-5. Also, we set the height for all tasks to 300. Does this match Mermaid's expected behavior? Let us know if you have any suggestions!
