Law of Uniform Connectedness

Things joined visually, such as by a line, are seen as more related than unconnected things.

Why it matters

Connections can show order or relationships more strongly than spacing.

How to use it

  • Use lines for steps in a process.
  • Connect a menu visually to its trigger.
  • Connect related data points in a chart.

Example

A line linking the steps of an order tracker shows they form one sequence.
