/**
* Display tag cloud.
*
* The text size is set by the 'smallest' and 'largest' arguments, which will
* use the 'unit' argument value for the CSS text size unit. The 'format'
* argument can be 'flat' (default), 'list', 'nolink', or 'array'. The flat value for the
* 'format' argument will separate tags with spaces. The list value for the
* 'format' argument will format the tags in a UL HTML list. The nolink value for the
* 'format' argument will display the tags without links. The array value for the
* 'format' argument will return in PHP array type format.
*
* The 'orderby' argument will accept 'name' or 'count' and defaults to 'name'.
* The 'order' is the direction to sort, defaults to 'ASC' and can be 'DESC'.
*
* The 'number' argument is how many tags to return. By default, the limit will
* be to return the top 20 tags in the tag cloud list.
*
* The 'topic_count_text_callback' argument is a function, which, given the count
* of the posts with that tag, returns a text for the tooltip of the tag link.
* @see default_topic_count_text
*
* The 'exclude' and 'include' arguments are used for the {@link get_tags()}
* function. Only one should be used, because only one will be used and the
* other ignored, if they are both set.
*
* @since 2.3.0
*
* @param array|string $args Optional. Override default arguments.
* @return array Generated tag cloud, only if no failures and 'array' is set for the 'format' argument.
