Version Compatibility

Reference examples tested with: matplotlib 3.8+, pandas 2.2+, scanpy 1.10+

Before using code patterns, verify installed versions match. If versions differ:

• Python: pip show <package> then help(module.function) to check signatures
• R: packageVersion('<pkg>') then ?function_name to verify parameters

If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.

UpSet Plots

"Visualize set intersections" → Replace Venn diagrams with UpSet plots for comparing overlaps across many gene/peak/variant sets.

• R: UpSetR::upset(fromList(sets))
• Python: upsetplot.UpSet.from_memberships() or from_indicators()
