Bug in NearestNeighborGraph

NearestNeighborGraph generates incorrect output on rasterized input. Reported to Wolfram support CASE:4093797

NearestNeighborGraph

$Version


11.3.0 for Mac OS X x86 (64-bit) (March 7, 2018)

NearestNeighborGraph[
Rasterize[Style[#, 20]] & /@ Alphabet, 2,
VertexLabels -> Automatic]


Is there a workaround?

Assuming you are asking for a workaround, you can generate the output you expect with:

v = Style[#,20]& /@ Alphabet;
rv = Rasterize/@v;

NearestNeighborGraph[
rv,
2,
VertexLabels->Thread@Rule[rv,v]
]


For another workaround, you can set ImageSize:

NearestNeighborGraph[
Rasterize[Style[#, 20], ImageSize -> 10] & /@ Alphabet, 2,
VertexLabels -> Automatic]
