The HTML <map> tag is used for declaring an image map.
The <map> tag is used in conjunction with the <area> tag and <img> tag to specify clickable areas (sometimes referred to as "hot spots") on an image.
To create an image map, you use the <map> tag to declare the image map, and the <area> tag (nested within the <map> tag) to define the clickable areas. The <img> tag can be defined elsewhere on the page, and is linked to the <area> element using the ID attribute.
