💡 Goal

Show the best days of the week and dates for selling online.

🤝 Acceptance Criteria

• [x] date with the most sales (black friday campaign) → in numbers. Total R$ revenue and date
• [ ] days of the week that e-commerce sells the most → heat map or similar

See the Notion reference with pictures as example

Solution for the first AC:

best_selling_date = ord_Nov_17['revenue($R1000)'].idxmax()
best_selling_revenue = ord_Nov_17['revenue($R1000)'].max()
print(best_selling_date,'Total Revenue($): ',format(best_selling_revenue*1000,'.2f'))

Instead of print use the propel form of streamlit like st.metric()

For the second AC i don't understand if we have to make a modification of the current heatmaps availables or a new one.

We only keep one from the originals. The heat map needs to highlight the best day and moment for selling online. Thank you, @felipesaldata!
