# PR Walkthrough Create a local static HTML/CSS/JavaScript walkthrough that orients a reviewer to the current branch's pull request as four separate interactive D3 views. The walkthrough should help the reviewer understand the affected code and the PR from four distinct views: - **System overview view**: a concise standalone code overview for the subsystem touched by the PR. It should not feel like a graph. Present it as a small set of expanded component cards that give the reviewer just enough architectural context to get their bearings before reviewing the PR. Do not mention the PR, changed files, review comments, diff links, screenshots, specs, or implementation deltas in this view. - **Data flow graph**: how state, data, events, requests, files, assets, or rendered output move through the changed system. - **Code dependency graph**: which changed components depend on each other, where the major seams are, and which files are entry points versus leaf dependencies. - **User action graph**: what the user does, what surface they interact with, and how that action flows through the implementation. This skill is an experiment in canvas-based PR comprehension. Do not reproduce the slideshow format. Do not put all perspectives on one graph. Generate four separate canvas views that the user can toggle between, and provide a guided tour within each view so the site teaches the PR from start to finish. Scale the walkthrough to the PR size: a small PR should feel like a compact revie
