Visualise Go program gctrace data in real time

Note: GC timing graphs are only supported for go 1.6

Running it directly:

env GOMAXPROCS=4 gcvis godoc -index -http=:6060

Adding the gctrace flag yourself:

GODEBUG=gctrace=1 godoc -index -http=:6060 2>&1 | gcvis

Or from a log file:

GODEBUG=gctrace=1 godoc -index -http=:6060 2> stderr.log
cat stderr.log | gcvis

Starting the server without automatically opening a browser:

gcvis -o=false godoc -index -http=:6060
