Word Cloud

Word clouds rank words by value (usually frequency) using size and color.

Generation Modes​

Columns supports two modes:

  1. Word + metric mode: one key field (word) and one metric
  2. Word-break mode: a text field that is tokenized into words and counted

A dedicated wizard helps generate word clouds in either mode.

Example output: Wordcloud Chart

Word Break​

Word-break can be enabled in both the wizard and chart settings.

Current word-break processing is client-side and may not scale well for very large text volumes. Backend scaling work is tracked here: https://github.com/varchar-io/nebula/issues/184

Choose word break

Settings​

Click the chart to open settings.

Available options include:

  • Rotation: random word angle
  • Spiral: placement pattern
  • Palette: color assignment
