Visualize the taxonomy graph of a given species

Contributed by: Keiko Hirayama

ResourceFunction["TaxonomyGraph"][species]

visualizes the taxonomy graph for a specified species entity.

Details and Options

TaxonomyGraph illustrates the evolutionary tree of an organism. Vertices represent hierarchically organized taxa arranged based on taxonomic ranks.
Any entities of "TaxonomicSpecies" can be used.
ResourceFunction["TaxonomyGraph"] has the same options as Graph.

Examples

Basic Examples (2) 

Visualize the taxonomy graph of an animal:

In[1]:=
ResourceFunction["TaxonomyGraph"][ Entity["TaxonomicSpecies", "AiluropodaMelanoleuca::fqjh7"]]
Out[1]=

Visualize the taxonomy graph of a plant:

In[2]:=
ResourceFunction["TaxonomyGraph"][ Entity["TaxonomicSpecies", "Quercus::k2384"]]
Out[2]=

Options (2) 

Highlight taxa of interest:

In[3]:=
ResourceFunction["TaxonomyGraph"][ Entity["TaxonomicSpecies", "LoxodontaAfricana::qtsb3"], GraphHighlight -> {Entity["TaxonomicSpecies", "LoxodontaAfricana::qtsb3"], Entity["TaxonomicSpecies", "Mammalia::5448z"]}]
Out[3]=

Specify the layout of a graph:

In[4]:=
ResourceFunction["TaxonomyGraph"][ Entity["TaxonomicSpecies", "DugongDugon::8b266"], GraphLayout -> "RadialDrawing"]
Out[4]=

Applications (1) 

Combine the taxonomy graphs of two species:

In[5]:=
species = {Entity["TaxonomicSpecies", "GiraffaCamelopardalis::y5488"], Entity["TaxonomicSpecies", "FelisCatus::ddvt3"]};
In[6]:=
GraphUnion[ Sequence @@ Map[ResourceFunction["TaxonomyGraph"][#] &, species], GraphLayout -> "RadialDrawing", VertexLabels -> Placed["Name", Tooltip], GraphHighlight -> species]
Out[6]=

Possible Issues (1) 

Trying to visualize the non-species entity returns a Missing value:

In[7]:=
ResourceFunction["TaxonomyGraph"][Entity["HorseBreed", "Barb"]]
Out[7]=
