Sankey view of Go heap dump

[bboreham]

My internal concept of this tool comes from the .Net CLR Profiler I used to use ten years ago.
Here is a description from MSDN Magazine.

The old CLR code is here

The Sankey view of which objects are retaining which other objects is (I think) just what you need when you can't figure out why the heap is so large.

The viewcore program seems a great place to start, though it needs some updating for Go 1.16 golang/debug#7 and golang/debug#5

Let me know if you ever build something like this :) Currently trying to get some use out of viewcore, but like you say, it's a bit outdated.

Over Xmas I tried to get viewcore more up-to-date: golang/debug@master...bboreham:go-debug:go-1-20

Unfortunately Go 1.22 moved it further away again.
