This tool generates 3D visualization of Go concurrency flow by analyzing its execution trace. To view the visualization you need a modern browser with WebGL support (pretty much any browser nowadays).

Its primary goal is to be an educational tool for Go concurrency. It works well with small programs that produce short traces (see Scale issues below).
