GitHub OCTO is a free online tool to visualize code structure from GitHub. Here it takes a GitHub repository from you and then generates a visualization that you can export as an SVG file or embed on your website. With code visualization, you will get the idea about different source code files in your project. With this, you can spot large code files and files hidden inside deep folder hierarchy.
You can even create a GitHub workflow for this and it will automatically keep generating the code visualization file for you. You can embed the file in the main Readme.md and do whatever you want. This feature is being offered by GitHub itself, so you can rely on it for longer time and it will never leave your GitHub repository with broken images.
