go-binsize-treemap: Render a Visualization of Go Executable Space Usage — This is easier to look at than explain in writing! Essentially it’s a tool that generates an SVG treemap of how the space inside a Go-produced executable is used. Not necessarily super useful, but fun to look at and could throw up some surprises. Bloaty is another tool that can help in this area and does a deeper analysis.
