Continuity

As explained in Everyday Data Visualization

A perceptual organization principle in which elements following a smooth or continuous path are seen as related.

Continuity is the tendency to group elements aligned along a smooth line or curve. Even when outlines or segments are missing, the eye follows the implied path and treats the pieces as related. section 2.2.5

Designers and data communicators use continuity in familiar ways:

• Logos can remain readable or recognizable without complete outlines because aligned marks suggest letters, shapes, or figures. section 2.2.5
• A donut chart remains legible as a partially missing circle because viewers mentally complete the continuous path. section 2.2.5
• Sorted bars are easier to scan because their bases form a straight line and their ends create a diagonal progression. section 2.2.5
• Sort by length only when category order is not meaningful; sorting a time series would scramble its chronology. section 2.2.5

How Everyday Data Visualization covers it

How deep it goes

Defines alignment along lines and curves, then explains examples and sorting caveats without developing perceptual mechanisms.

Examples

Uses recognizable logos, text baselines, donut charts, and sorted horizontal or vertical bar charts.

What it assumes

Assumes only familiarity with everyday visual perception and basic charts; introduces the Gestalt framing conversationally.

What you can do after

Evaluate/understand it by arranging visual elements along coherent paths and protecting meaningful category or time order.

How it connects

Connects continuity to closure, connection, Gestalt principles, grouping, alignment, and data visualization.
