 The `aria-describedby` attribute is used to provide additional descriptive information for an element, which can be especially useful for users of assistive technologies. By linking the element to another element that contains the description, screen readers can convey more context and details to users, enhancing their understanding and interaction with the web content. This is particularly important for complex elements like maps, where visual information needs to be translated into meaningful text descriptions.
 
+### Why Use `aria-describedby` Instead of `aria-label`
+
+While both `aria-describedby` and `aria-label` are used to provide accessible descriptions, they serve different purposes. The `aria-label` attribute is used to provide a concise, accessible name for an element, which is typically short and to the point. In contrast, `aria-describedby` is used to link an element to another element that contains a more detailed description. This is particularly useful for complex elements like maps, where a brief label would not suffice to convey all necessary information. By using `aria-describedby`, we can provide users with assistive technologies a richer, more informative description that enhances their understanding and interaction with the map.
