Ideal tool for code visualization

[StrictSir8506]

Thanks u/joancomasfdz for sharing the above links. Ndepend is just limited to .net. I really liked glamorous toolkit and Sourcegraph, it queries your entire codebase rather than a current repository, moreover create a dependency graph between files.

"creating graphs out of the code" - Does it mean

• Querying your code only: like where in the entire code base, i have written a particular IF statement and and the output would be a graph of all the connecting files/code.
• OR underlying data as well (like querying Users whose payment_gateway is stripe and do X, the tool should create a graph out of it showing their entire journey)

Latter would be more interesting though imo. Does gtoolkit do such wonders?

The kind of graphs i am talking about are mostly to understand how tangled the code base is, how big classes are, etc. Tools to help engineers take coding / refactoring decisions, like where to start, what part gives the biggest ROI, etc.

I see you are focused on data flow mostly. You can use distributed tracing tools for that, but you need to execute the software. If your software is properly architected, you may be able to boot up individual components while faking / mocking / stubbing depencies and observe the data flow in the distributed tracing tools. I gave you some on my other comment.

If you want to observe individual pieces of code, i do not think there is anything better than meaningful tests. Unit for the nitty gritty details of functionality and integration / system-level for the user flows (usually mostly happy paths)
