Software Visualization: The humane solution
summary
Developers spend most time reading code—estimates cited are ~78% of work and ~20 million developers globally—so visualization must speed comprehension. A node‑link graph with node colors for types/functions/variables, edge bundling and an active-symbol layering (bases above, derived below, users left, used right) surfaces dependencies without overwhelming scale. Implemented in Sourcetrail using LLVM/Clang LibTooling and Eclipse JDT Core, the approach ties interactive graphs to source, shows calls and accesses on click, and trades perfect completeness for much faster, focused understanding.
