Thanks for providing great visualizations of YAML and JSON
With some nested YAML and JSON, the results become very wide, and I'd like the possibility to make the visualization fit better.
The current functionality is that changing the direction on diagrams that embed YAML and JSON does not affect the YAML or JSON visualization (which is always left to right direction), while it does affect the rest of the diagram, as seen when modifying the Self Descriptive Example on the preprocessing JSON page (https://plantuml.com/preprocessing-json)
One way the goal could be supported, is by being able to selectively change the orientation of the YAML or JSON visualization to use "top to bottom direction" or not, without affecting the overall chart, to make it fit better.
/edit: Updated title and text to reflect my new understanding that the YAML and JSON visualization is currently always left to right direction, and it would be good to make it go top to bottom.
