Show HN: I added stacked subgraphs to Mermaid flowcharts

A developer using the handle ramraj07 published a fork of Mermaid called ra-mermaid on GitHub that adds a new "stack layout" syntax for stacked subgraphs in flowcharts, addressing Mermaid's limitation that subgraphs do not follow direction when internal nodes connect to outside nodes. The developer said the change was produced by prompting Claude and also added local-storage snapshot saving to the mermaid.live playground. The Show HN post drew 1 point and 0 comments.

I’m an avid user of mermaid but am constantly annoyed by their limitation that subgraphs do not follow direction if any internal nodes are connected to the outside. So I asked Claude to add a new syntax called stack layout and it seems to work pretty elegantly. I also fixed my annoyance with mermaid.live and allowed this playground to save snapshots in your local storage as well. Happy to add more storage features if anyone’s interested The one prompt fork is at https://github.com/ramraj07/ra-mermaid https://github.com/ramraj07/ra-mermaid Comments URL: https://news.ycombinator.com/item?id=50236250 https://news.ycombinator.com/item?id=50236250 Points: 1 Comments: 0
