#### Graph Explanation
The graph, located in the upper-right corner, displays a line plot representing the price of apples over a year.
- **X-axis (Time):** Month names from January to December.
- **Y-axis (Apples):** Price of apples ranging approximately from 0.9 to 1.3.
- **Description:**
- There is a fluctuation in prices with a noticeable increase during mid-year, reaching its peak around July or August.
- A subsequent decline is observed towards December.
**Purpose:** The graph visually complements the data table, allowing for a quick understanding of trends in apple pricing throughout the year.
By using the 2-point moving average, one can smooth out these monthly fluctuations to better identify trends and predict future prices.
