Bubbles represents the relative frequency of words in a corpus through a cloud of bubbles. Each word is represented by a bubble, where the size of the bubble is proportionate to the frequency with which the word occurs in the corpus. The larger the bubble’s radius the more frequently the word occurs.

Getting Started

When you first arrive to the Bubbles tool you will see one of two possible screens:

Bubbles without a pre-loaded corpus. See loading texts into Voyeur for help on how to proceed.

Bubbles with a pre-loaded corpus. You were probably given a URL that included the corpus, or you’re viewing a page that has an embedded Voyeur tool in it. If you prefer, you can also start without a corpus.

Interface Elements

Bubbles includes the standard set of interface elements (see image to the right). For more help with these see the Voyeur Tools Standard Interface Elements page.

Reading the tool

As Bubbles loads, you will see a list of words. The higher the word is on the list, the higher frequency it has within the corpus. The same applies for the bubbles – the larger the bubble, the higher frequency it has within the corpus.

Different sizes of bubbles

At the bottom left of the screen, the tool displays the number of bubbles displayed out of the possible words in the corpus. If the number is increasing, this means Bubbles is still loading more words.

Number of terms in the corpus



Like all Voyeur tools, Bubbles can be reused in a variety of ways:

  • create a link that is specific to the corpus and options that are currently being used
  • embed the current corpus and options as a tool in an external page

For more information see exporting and reusing Voyeur Tools.
