linked list stack 3d model

A 3D isometric educational model of a linked stack (singly linked list implementation of stack), computer science visualization. - Four nodes arranged horizontally from left to right, representing stack top to bottom: - Leftmost node (top): purple data cube labeled "3", attached to a smaller gray pointer cube labeled "next" - Second node: yellow data cube labeled "2", with gray "next" pointer cube - Third node: blue data cube labeled "1", with gray "next" pointer cube - Rightmost node (bottom): red data cube labeled "0", with white pointer cube labeled "null" - Each data cube is larger than its adjacent pointer cube; both share the same height and are flush-aligned. - Black curved arrows connect each "next" pointer cube to the data cube of the next node. - A bold red arrow labeled "Top" points downward to the leftmost (purple) data cube. - Clean, minimalist, technical illustration style, isometric view, soft ambient lighting, no background.
