Word cloud

Use a word cloud for a first look at which words matter most in a text or a list of topics. Reach for a bar chart when readers need to compare the values.

```chart

title: Dashboards and forecasts lead what readers ask for
subtitle: Requests per topic over one quarter, illustrative counts
data:

Fields that matter

• type: wordcloud with encoding.label for the word and encoding.y for its value, such as a count
• A word’s size follows the square root of its value between the smallest size the chart text allows and a largest that fits the plot, on one scale in every panel; words are set horizontally and coloured along the style’s ramp by the same value
• Words go in from the largest to the smallest at the first free place out of the centre, so the same data always gives the same picture
• A word that finds no room is not drawn and is reported, and stays in the readouts and the table; a panel takes at most 150 words, and above that the chart is not drawn and check raises chart.limit-exceeded naming the limit and the count
• A row without a word or a value above zero is left out and reported
• The share in a readout is computed by RichView and marked as derived
• encoding.facet makes one cloud per value; axes.y.label names the value

Interactions

• Hover or focus a word to read its value and its share.
