Disclosed are various embodiments for generating interactive maps for browsing items in a catalog. A first map of items that includes graphical representations of each one of a first set of items is generated. A selected item is determined according to a selection of one of the graphical representations of the first set of items. A second set of items is determined based at least in part on similarity of the second set of items to the selected item. A second map of items that includes graphical representations of each one of the second set of items is generated. The graphical representations of each one of the second set of items are arranged in the second map of items relative to the graphical representation of the selected item based at least in part on a corresponding degree of similarity of the respective item to the selected item.
