in the wild¶

build it up¶

A <v-click>-style build-up of one Mermaid flowchart: seven steps, each revealing exactly one more piece of the architecture, with the narration a speaker would say over it. Asked for in slidevjs/slidev#1498 (https://github.com/slidevjs/slidev/issues/1498), where duplicating the diagram per slide made elements shift and visibility:hidden left the arrows behind.

walk the pipeline¶

Step-by-step presentation of one diagram, greyed out rather than hidden: the whole pipeline is on screen from the first beat, and the parts the story has not reached yet are faded back instead of removed. Asked for in mermaid-js/mermaid#7710 (https://github.com/mermaid-js/mermaid/issues/7710): advance on click or space, grey out what is still to come, and have a way to highlight specific elements.

one polling cycle¶

A twenty-message poller-and-webhook sequence diagram, exactly as posted in mermaidjs/mermaid-live-editor#53 (https://github.com/mermaidjs/mermaid-live-editor/issues/53) — the 2019 "Animated Diagrams" request whose author found larger diagrams "a bit overwhelming" and built a proof-of-concept to animate this one.

auth refresh edge cases¶

One diagram, three scenarios: a token refresh that works, a refresh token that was already rotated by a concurrent login, and an identity provider that does not answer. The happy path is the only thing drawn at full strength; the two edge cases are variant scenarios that replay it up to the exact hop where reality diverges and then tell their own ending. The shape of the question comes from r/webdev (reddit.com/r/webdev/comments/1u87ptj): "the happy path is clean but the edge cases are killing the diagram."

claude code tool call¶

What actually happens when Claude Code runs a single tool call, end to end: one prompt, one round trip through the model, one Bash invocation against the repo, and the answer that comes back. Drawn for the people in anthropics/claude-code#14375 (https://github.com/anthropics/claude-code/issues/14375) who use Claude Code to map out codebases and wanted real diagrams instead of ASCII art.
