How to stretch line length

[wangdayong228]

This is the graph made by mermaid.

I want enlarge the link line as follow, could mermaid do this work? Maybe use linkstyle or set a factor for stretch line length?

except replay, thank you guys.

AFAIK this cannot be adjusted in mermaid at the moment. According to this comment there are graph settings in dagreD3 which allow to set the distance between nodes. Perhaps these can be added to the flowchart config attributes and used for setGraph() in the flowchart renderer?

However, these settings would apply to the entire graph layout, not to a selection of nodes/connection lines.

The settings nodesep and ranksep can be used to put more space between the nodes (both 50 by default); as mentioned above, this is applied to all the nodes in the graph.

nodesep is the spacing value for nodes of the same rank, while ranksep holds the spacing value between ranks. In a top-down graph for example, "nodesep" could be seen as the horizontal spacing while "ranksep" does the vertical spacing.

I'm going to provide a PR to make the settings available in the flowchart configuration.
