Create Charts and Visualizations with ChatGPT

I uploaded a dataset. Your job is to produce decision-grade visualizations.
First, inspect the dataset and write a 10-bullet data audit:
columns, types, missing values, duplicates, weird categories, time granularity, likely data quality risks

Then propose 5 different chart options that answer the most important decision questions in this data:
for each: chart type, what it shows, why it matters, and the exact fields used

Create the best 3 charts with these rules:
clean design, minimal colors, clear title, labeled axes with units, readable ticks, no clutter
annotate key points (peaks, drops, breakpoints)
include 1 sentence takeaway under each chart

Validation step:
list 5 checks you performed to ensure the charts are accurate
if anything is ambiguous, stop and ask only the minimum clarifying question

Output:
deliver the charts and also provide the code used to generate them in Python (matplotlib) or JavaScript (Plotly), my choice: Python
