Could you build this?
Partial The UI for showing a visual guide is vibe-codeable, but generating accurate file, function, and flow maps for arbitrary repositories needs real code-analysis infrastructure (parsing, call graphs, indexing) that is harder to get right than the frontend.
What it would actually take: A real version would combine tree-sitter or language-server based parsing to build a symbol and call graph, embeddings or retrieval over the repo, and an LLM pass that selects the files relevant to a given issue. The React/graph visualization is the easy part. The hard part is making the relevance and flow output reliable across many languages and large codebases, which takes experience with static analysis and evaluation against real issues.
