Basic Code Exampls of Dash

Below, are the code example of Dash .

Example 1: Create Basic Dash App

In this example, below Python code utilizes the Dash framework to create a simple web application with a line chart. It imports necessary libraries, defines a Dash app with a basic layout, and generates a line chart using sample data. When executed, the app runs in debug mode, allowing visualization of the line chart at a specified server address.

To run this example, save the code in a file (e.g., simple_dash_app.py) and execute it. Open your web browser and navigate to
