Numerical with Frequency

The Numerical with Frequency strategy allows visualizing triplets as coordinates (x, y) with an associated numeric frequency.


It attempts to answer the following sensemaking task:

  • What is the relationship between three numeric variables?

Presentation metaphor

Data, together with Numerical.

Context meta-model

The context meta-model of Numerical with Frequency contains a single class, Target, with three numeric attributes: x, y, and freq.

Visualisation variants

  • Bubble Chart displays coordinates as bubbles with a size proportional to the frequency freq.
