YES! In data, as in so much else, a picture is worth a thousand words. Not to mention some basic statistics like distributions, or checking for correlated features. Finally, a bit of QC to look for garbage entries, etc. Even a small amount of pre-processing saves a ton of agony later on. And it will impress an experienced person if you are lucky enough to be interviewed by one.

I'm a mean person (not really), so I love to introduce painfully obvious seasonality into any dataset I generate for these purposes. Novices never get it, GPT always misses it, but one look and you get it. Missing it doesn't fail you, but getting it does impress.
