Dash, on the other hand, is a Python framework for building web applications that are powered by Plotly visualizations. It allows you to create interactive dashboards, data-driven applications, and other web-based tools using Python code. Dash provides a simple and intuitive way to build custom web applications without requiring expertise in web development or JavaScript.
The combination of Plotly and Dash provides a powerful set of tools for data visualization and web application development. With these tools, you can create sophisticated data-driven applications that allow users to interact with data in real-time, explore complex relationships, and gain insights into large datasets.
