Behind every clean chart is a messy spreadsheet 🧹
This is what a real data cleaning job looks like before it becomes an elegant bar chart — duplicate rows, missing values, inconsistent formatting, all sorted out with Python and Pandas.
#collage attempt: a look inside the data analyst's actual desk, not just the pretty output.

The part where you pull out duplicate rows with Pandas before the bar chart really highlights the messy prep that most people never see.

Thank you so much Johnson! Appreciate you noticing that part. Most people skip the cleaning and go straight to charts, but that’s where 80% of the work is. Glad this helped highlight it!
