A loading animation is a visual cue that indicates a process is ongoing, typically while data is being fetched or a program is starting. These animations can take various forms, such as spinning icons, progress bars, or pulsing dots, and are designed to keep users informed and engaged during wait times. Loading animations are commonly used in software applications, websites, and mobile apps to enhance user experience. By providing feedback, they help reduce frustration and uncertainty, making it clear that the system is working on a task, such as retrieving information or processing a request.
