Create a graph of symbol dependencies

Contributed by: Richard Hennigan (Wolfram Research)

ResourceFunction["SymbolDependencyGraph"][symbol]

displays a Graph corresponding to the symbol dependencies of symbol.

Details and Options

An edge a→b will appear in the graph if the symbol b appears in the definition of symbol a.
ResourceFunction["SymbolDependencyGraph"] takes the same options as Graph.

Examples

Basic Examples (1) 

Graph the dependencies of a symbol:

In[1]:=
a := Hold[b, c]; b := 1; c := d; d := Hold[a, b, e]; e := 2; ResourceFunction["SymbolDependencyGraph"][a, VertexLabels -> "Name"]
Out[6]=

Scope (1) 

See how a function relies on other functions:

In[7]:=
ResourceFunction["SymbolDependencyGraph", ResourceVersion->"1.0.1"][GeneralUtilities`PrintDefinitions, VertexLabels -> Placed["Name", Tooltip]]
Out[7]=

Applications (1) 

See how symbols in a context are related:

In[8]:=
symbols = ToExpression[Names["GeneralUtilities`*"], InputForm, HoldComplete];
In[9]:=
g = ResourceFunction["SymbolDependencyGraph"][symbols, VertexLabels -> Placed["Name", Tooltip]];
In[10]:=
VertexDelete[g, "symbols"]
Out[10]=
In[11]:=
GraphPlot[%]
Out[11]=
