Regarding visualization of codebases, something I've wanted for a long time is a graph of function calls across an entire project.<p>I want to know all the callers and callees of every function. This shouldn't be too hard, we already have find references via LSP.<p>Turning this into a graph would make it significantly easier to manage the entry and exit points of a code base and inform architecture decisions, refactors, type checking, hot paths etc.
