The first picture uses a simple grid layout while the second picture uses a force-based layout. Both pictures show the same results. \n\nThis was done as a simple programming exercise. If you have a wishlist, enter it in as an issue.\n\nThe source code of GWBasic is written in Assembly is made of over 34K LOC, spread in 35 files, totalling over 3.6K Assembly inter-connected routines. Here are some visualization that illustrates the routine interaction.\n\n![alt](screenshots/routine-graph1.png)\n\n![alt](screenshots/routine-graph2.png)\n\n\n-----\n\nOn the very same tone, here is [MSDOS Version 1.25](https://github.com/microsoft/MS-DOS). MSDOS 1.25 is 13K LOC long made of 1,573 Assembly routines. Here are their connections:\n\n\n![alt](screenshots/msdosV1.25.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbergel%2Fgwbasicvisualization","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbergel%2Fgwbasicvisualization","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbergel%2Fgwbasicvisualization/lists"}
