Tag Cloud Demo
This demo shows how to create a
Tag Cloud
visualization.
Tag clouds are a standard tool for visualizing text documents. The number of occurrences
of a word in the text document is the word's
frequency
. The higher the frequency of a word, the more significant the word is. To convey a word's
significance, its frequency determines the font size and text color of the word in the tag
cloud. More frequent words are shown with increasingly larger font sizes.
For brevity's sake, the demo does not actually process word documents to calculate word
frequencies, but uses prepared frequencies of a fictional document as its input.
Things to Try
-
Switch between two arrangement styles for the tag cloud,
Circle
and
Rectangle
.
-
Use the
Word Frequency
slider to determine the minimum frequency for word to be included in the tag cloud.
