Routing Highlight Path Annotation for hidden grandparents connections
The connection lines are hard to trace on the screen visually. They make sense for traditional paper form diagrams visualization when we have no interactivity. But they bring no value for interactive applications, so the main point is to remove redundant connection lines giving no visual value and replace them with dynamic highlight path annotations and custom node templates for compensation.
