You can display a tag cloud of metadata properties with with the tagcloud tag:

{{tagcloud  type="metadata type to display"
types="optional comma separated list of types"
width="100%" height="600px"
threshold="number - minimal number of occurrences to display"
colorTable="optional color table"
style="css style of the word cloud background"
delay="milliseconds to use to delay the drawing of each word"
}}

The list of metadata types can be viewed at /repository/metadata/types.html.
The list of color tables can be viewed at /repository/colortables

For example, here we are displaying a number of the Archive metadata properties:

{{tagcloud  type="archive_keyword" types="archive_keyword,archive_category,archive_subject,archive_term"
width=100% height=600px threshold="0"  colorTable=plotly_blues
style="background:#efefef;border:1px solid #ccc;" delay=1
}}
