The sentiment scores are categorized into positive, neutral, and negative sentiments. The chart includes the following key elements:

• Average Daily Sentiment (Blue Line): This line represents the average sentiment score for each day. It shows how customer sentiment fluctuates over time.
• Average Sentiment (Orange Dashed Line): This horizontal line represents the overall average sentiment score across all days.
• Upper Bound (Red Dashed Line): This line represents the average sentiment plus one standard deviation. It indicates the upper range of typical sentiment scores.
• Lower Bound (Green Dashed Line): This line represents the average sentiment minus one standard deviation. It indicates the lower range of typical sentiment scores.

How to Interpret the Chart:
- When the blue line (daily sentiment) is above the orange line (average), it indicates better-than-average sentiment.
- When the blue line is below the orange line, it indicates worse-than-average sentiment.
- If the blue line crosses the red or green dashed lines, it suggests unusually high or low sentiment, respectively.
