## What it is
GoTrace is a CLI tool that analyzes Go execution traces produced by the Go runtime and renders a 3D WebGL visualization of concurrency flow in the browser. It is primarily an educational tool for understanding Go's goroutine and scheduler behavior in small, short-running programs.

## Use cases
- visualize goroutine concurrency in 3d
- understand go scheduler behavior
- teach go concurrency patterns
- analyze go execution traces visually
- debug goroutine interactions in small programs
- render go trace files as webgl animation

## When to choose
- you are learning or teaching Go concurrency concepts
- you want an intuitive visual view of goroutine scheduling in short traces
- you want to explore how channels and goroutines interact over time

## When to avoid
- you need production performance profiling of long-running programs
- your traces are large or your program runs for a long time
- you need standard go tool trace analysis rather than 3D visualization
- you cannot patch the Go runtime or use the provided Docker image
