Analyzer go-excep-fgraph

# Name

go-excep-fgraph - Go-Land Exception Flame Graph

This analyzer captures and visualizes panic and error handling paths in Go applications. It generates flame graphs showing the call stacks where panics occur or errors are generated, helping developers identify error-prone code sections and understand exception propagation patterns. The analyzer is valuable for improving error handling strategies and application reliability.
