How do you visualize code?

For run-time visualization, I use Chrome about://tracing it gives very good details, over a time horizon, synchronized over multilple threads/processes. Zoom into nanosecond detail or zoom out over seconds or minutes overview.

I have my own simple C++ code to generate those traces (json data), there is also an official sdk for it (Perfetto is the new shiny way)

For static code analysis, I use Doxygen, it parses the headers, can make high level module diagrams and fine grained dependency graphs. It uses Graphviz/dot for rendering the graphs.

Quite interesting application of tracing tools, I've only used it for build time optimizations. Do you perhaps have a screenshot to see how the end result would look like ?

Here is a quick video, where you can see all the frames when zoomed out, and detailed frame information when zoomed in https://www.youtube.com/watch?v=w2rz36aJUS4 This is just for a physics engine, with rendering.

Thanks for the effort of creating the video. It looks like it would be useful in a similar sense perf flamegraphs are.
