Two dots joined by a line — paired comparisons.
Each row has two dots (e.g., before / after, group A / group B) connected by a line. Reads as "this category went from A to B".
When to use
Paired comparisons across many categories where the GAP between the two is the point.
When NOT to use
You have 3+ time points (use line per category).

- If a thin line connects two columns of dots, it is slope (no horizontal alignment).
