(we are probably now a bit off-topic) This is close to what we have in
SHACL Play with SHACL generation :
https://shacl-play.sparna.fr/play/generate#documentation. It generates
SHACL by analyzing the structure of the dataset, and complements this by a
VOID statistics file (see example at the end). In our case we analyze the
statistics *from / after* the SHACL generation, we don't derive the SHACL
from the statistics.

What I would find useful in this context would be to relate the VOID
statistics file not to classes and properties, but to actual shapes (i.e.
void:shapePartition instead of void:classPartition). Because the statistics
could be computed from shapes with e.g. SPARQL targets.
