@aucahuasi - it is failing for test-full-ai, unsure how to fix that. Known issue? |

add signature to
Plottableinterface: https://github.com/graphistry/pygraphistry/blob/master/graphistry/Plottable.py -
expose for chained use in
PlotterBase, e.g., :pygraphistry/graphistry/PlotterBase.py

switch from print statements to warn + logger.info depending on use
removes need for verbose param via Pythonic conventions

node existence should be more like:
- either _node and _nodes are both defined or neither defined

for validators used for debugging, instead of doing an immediate error, good to collect errors and report them all, with failure only at the end

compute & report .sum() vs just .any()
a more verbose mode might return the df to help save time

why not returning False?

Good point, I guess I was considering only graph with edge IDs that could be valid.
However, to your point, we should error if g._node and g._nodes exist and there are missing node IDs from g._edges src/dst, that should throw an error.

as a public function, should have a docstr matching other docstrs format

bigger picture:
-
always-on for validated uploads: factor out fast metadata-only checks (e.g.,
validate_schema_bindingsbinding name <> col name match up) from data-level checks (e.g.,validate_indexeschecking col for nan, value mismatches, etc): updateArrowUploader::create_dataset->if validate: ...to include the fast metadata-only checks. Arguably we should do data-level checks here too, but that changes perf characteristics more fundamentally so let's not for now.. -
expose on
Plotter/PlotterBase, ideally calling both this +validate_encodings -
switch to
logging/warnvsverbse => print(), and report error count (# hits per violated condition) and ideally all errors vs early-exist on first -
add an ipynb demo
-
some potential items to warn or error on

recommend also checking that dtypes of src/dst match, as does node/src if exist
type mismatch is more of a warning vs a fail, as we can support bipartite graphs, like imagine user:str <> day:int

likewise, as a warn vs fail, if there is no overlap of src/dst edges, they may have a mismatch needing cleanup, imagine 123 <> id:123
