this article is confusing, it appears to conflate graphviz (an umbrella term/tool that collects a set of layout engines and output formats) with both dot (a specific layout engine) and sstangl/iongraph (a specific tool that transforms a particular SSA/AST input format to a specific dot output format)

it also seems to conflate how a DAG is expressed, with how that expression is rendered

strange
