Ramraj07

Ramraj07 is a modified Mermaid playground that adds a new "stack layout" syntax for flowchart subgraphs. In standard Mermaid, subgraphs do not follow their set direction when internal nodes connect to nodes outside the subgraph. The author asked Claude to build this layout, and it is presented as a working alternative for that case.

The playground can also save diagram snapshots to browser local storage. The author says more storage features may be added based on interest. A GitHub link to the prompt fork is provided on the page.
