The word "visibility" refers to how easy or difficult it is to see something. For example, if it's very foggy outside, the visibility might be low, meaning that it's hard to see very far in front of you. Or, if you're trying to find a website on the internet, you might need good visibility to find the website quickly and easily. In any situation where you need to be able to see something clearly, visibility is an important factor to consider.
