Dash is a powerful open-source framework developed by Plotly, designed for creating interactive web applications using Python. It allows users to build data visualization interfaces without needing extensive knowledge of web development technologies like HTML, CSS, or JavaScript. Dash applications are composed of two main components: layout, which defines the visual structure, and callbacks, which manage interactivity. This makes Dash particularly appealing for data scientists and analysts who want to present their data insights through interactive dashboards. With Dash, users can easily create, customize, and deploy applications that visualize complex datasets in a user-friendly manner.
