I gave this a bit of thought earlier this year (https://alexanderell.is/posts/visualizing-code/ https://alexanderell.is/posts/visualizing-code/) and, with the help of HN commenters, collected a small list of ways people are working to help with code visualization. I don't think most of them are production ready (some are just research papers), but you may find them interesting all the same. SoftVis3D (https://softvis3d.com/ https://softvis3d.com/): where a "‘code city’ view provides a visualization for the hierarchical structure of the project". Code Park: A New 3D Code Visualization Tool (2017) (https://arxiv.org/pdf/1708.02174.pdf https://arxiv.org/pdf/1708.02174.pdf), a “novel tool for visualizing codebases in a 3D game-like environment” with code represented as “code rooms” with code on the walls. Code Structure Visualization Using 3D-Flythrough (2016) (https://opus-htw-aalen.bsz-bw.de/frontdoor/deliver/index/docId/658/file/ICCSE16-SEE.pdf https://opus-htw-aalen.bsz-bw.de/frontdoor/deliver/index/doc...), with spatial metaphors and first-person exploration of code. Primitive (https://primitive.io/ https://primitive.io/), a VR collaboration startup with a Matrix-looking “Immersive Development Environment” with “new tools for visually analyzing software in 3D”. AppMap (https://appland.com/docs/how-to-use-appmap-diagrams.html https://appland.com/docs/how-to-use-appmap-diagrams.html), an automated code analysis tool that includes dependency maps and trace views. plurid (https://github.com/plurid/plurid https://github.com/plurid/plurid), a framework for visualizing and debugging code in a 3D explorable structure. fsn (file manager) (https://en.wikipedia.org/wiki/Fsn_(file_manager) https://en.wikipedia.org/wiki/Fsn_(file_manager)), an experimental application to view a file system in 3D (featured in Jurassic Park).
