Alignment Diagram with Vertical Selection Line and Row Markers #202121 (License: Personal Use)

This diagram features a bold red vertical line intersecting three horizontal rows, each containing a black-outlined circle on the left side, suggesting selected or highlighted elements. The clean, minimalist structure implies use in technical documentation, software UI wireframes, or algorithmic flow illustrations where alignment or conditional selection is demonstrated. The consistent spacing and symmetry emphasize clarity and logical grouping.

Commonly used in UX/UI design guides, developer documentation, or educational content explaining table selection, grid alignment, or state mapping; matches user intent to understand visual logic in structured layouts.
