 Dash is an open-source framework for building analytical web applications using Python. It is particularly useful for creating interactive, data-driven dashboards without requiring extensive knowledge of web development. Dash is ideal for data scientists and analysts who want to visualize complex datasets and share interactive results with others.

 Dash components are the building blocks of Dash application layout, enabling you to create interactive, web-based data visualizations using Python. Major categories of Dash components include:
 * **[HTML components](#html-components)** (`html`): Basic HTML elements like headings, paragraphs, divs, etc.
 * **[Core Components](#core-components)** (`dcc`): Higher-level components like graphs, dropdowns, sliders, etc.

 * **[Callbacks](#)** : Functions that enable interactivity by linking inputs and outputs.
 
 These components are integrated into the layout of a Dash application to create a user interface that responds dynamically to user interactions. *For example, a dropdown component can store options that filter or switch data on a plot interactively when selected by a user.*
