Word Cloud widgets
Word Cloud widgets are a visualization of a set of words, where the size and placement of a word is determined by how it is weighted as illustrated in the example below:

Word Cloud widgets are populated with data from CSV datasets, in which data is in tabular form. The information can be updated in response to events, either those at the dashboard level or those triggered by other widgets.
Having added a word cloud widget to a dashboard, you need to perform some configuration of general settings and the dataset that is used to populate the widget with data, and also some further configuration that is specific to word cloud widgets.
