The generated SQL uses Date as X-axis instead of SKU, and the chart is NOT a bar chart at all.
plt.figure(figsize=(10, 5))
plt.plot(df['Sold_Date'], df['Total_Sale_Value'], marker='o')
plt.title('A bar chart of sales by product SKU. Put the product SKU on the x-axis and the sales on the y-axis.')
plt.xlabel('Date')
plt.ylabel('Total Sale Value')
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()
