Create a fully-functional mini-application using Apache Superset that serves as a dashboard for monitoring sales performance across different regions. This application should allow users to visualize sales data from multiple sources and provide insights into regional sales trends. Here’s a detailed breakdown of the requirements:

1. **Data Sources**: Integrate at least three different data sources into your application. These could include CSV files, SQL databases, or even APIs that return JSON data. Ensure that each data source contains relevant sales data such as product categories, sales amounts, dates, and regions.

2. **Dashboard Design**: Design an intuitive dashboard that allows users to easily switch between different data sources and view sales performance metrics. Include widgets like line charts, bar graphs, pie charts, and tables to display key information.

3. **Custom Metrics**: Implement custom metrics that calculate important KPIs such as total sales per region, average sales per product category, and year-over-year growth rates. These metrics should be dynamically calculated based on user-selected time frames.

4. **User Authentication**: Add basic user authentication functionality so that only authorized users can access the dashboard. Users should be able to log in with their credentials and have roles assigned to them, allowing different levels of access depending on their permissions.

5. **Real-Time Data Updates**: If possible, incorporate real-time data updates from one of your data sources to demonstrate how the dashboard can reflect current sales figures.

6. **Mobile Responsiveness**: Ensure that the dashboard is mobile-responsive, providing a seamless experience for users accessing it via smartphones or tablets.

7. **Documentation**: Provide comprehensive documentation detailing how to set up and run the application, including instructions on installing dependencies, configuring data sources, and setting up authentication.

**Utilization of Apache Superset**:
- Use Apache Superset’s built-in data connectors to integrate your chosen data sources.
- Leverage Superset’s visualization capabilities to create interactive charts and graphs.
- Employ Superset’s security features to manage user authentication and role-based access control.
- Utilize Superset’s SQL Lab feature to perform ad-hoc queries on your data sources.
- Explore Superset’s alerting system to send notifications based on specific conditions or thresholds.

This project will not only showcase Apache Superset’s powerful BI capabilities but also provide valuable insights into sales performance through a visually appealing and user-friendly interface.
