The Exponential Smoothing Tool is an interactive tool designed to help users smooth out time series data using the Exponential Smoothing (ES) technique. Exponential smoothing assigns exponentially decreasing weights to past observations, giving more importance to recent data points. This method is widely used in forecasting and trend analysis.

Key Features:

1. Dynamic Input : Users can input their time series data as a comma-separated list and specify the smoothing factor ($\alpha$).
2. Customizable Smoothing Factor : The smoothing factor ($\alpha$) can be adjusted between 0 and 1 to control the weight of recent data.
3. Interactive Visualization : A line chart displays the original data alongside the smoothed data for easy comparison.
4. PDF Download : Export the generated exponential smoothing results and visualization as a PDF for sharing or reporting purposes.
5. Modern Design : Clean and stylish layout with vibrant colors and clear typography for better readability.
6. Self-Contained : The tool operates within its own container, ensuring it doesn’t interfere with the page header or footer.

Use Cases:

• Forecasting : Businesses and analysts can use this tool to forecast future values based on historical data.
• Data Smoothing : Researchers can reduce noise in time series data to identify underlying trends.
• Reporting : Professionals can export exponential smoothing charts to include in reports or presentations.

How It Works:

1. Introduction : Exponential Smoothing (ES) smooths time series data by applying a weighted average to past observations. The smoothing factor ($\alpha$) determines the weight given to recent data points: higher $\alpha$ values prioritize recent data, while lower $\alpha$ values give more weight to older data.
2. Input Fields : Users enter their time series data as a comma-separated list and specify the smoothing factor ($\alpha$).
3. Visualization : The tool generates a line chart displaying the original data and the smoothed data for easy comparison.
4. Export : Users can download the exponential smoothing results and visualization as a PDF for further use.
