Example 1 : Tag cloud of variable names (in alphabetical order or in order of the dataset): Fontsize represents e.g. the proportion of missing values. Example 2 : Tag clouds of values/value labels of a categorical var (with many strata like postcodes in a region). Fontsize represents an aggregated
score in each stratum.


Both of these cases can be better handled by using simple barcharts with the bars ordered from highest to lowest. The excellent -mrtab- and -mrgraph-, written by Ben Jann, are very versatile in this respect.

Tag clouds are usually sorted alphabetically, making the relative size of each tag hard to assess, since tags you may want to compare are in different places. If you sorted them by magnitude, of course, the fun aspect of tag clouds would be lost.
