Sample text

As you can see, the words in Figure 19 are far too small. We probably don't wantto see a font size smaller than about te so let's add ten to the count. We'llchange the line that converts tag count to font size from this: $fsize = $cnt; 39 40 to this: $fsize = $cnt+10; This change produces the tag cloud shown in Figure 20. Figure 20. Minimum font size of ten points This looks OK, but there are a few problems. The word "music" is really big, butall the other words are quite small. I'd like to s a little more variety in the fontsizes.

Many of the intermediate font sizes won't get used at all because of the larger gaps between the counts of the most popular word The way to make this tag cloud look better is to use a logarithmic function to reverse the power curve's effects. Essentially, we will map the linear range of font values to the logarithmic range of tag counts, magnifying the differences between smaller coun and making the "long tail" of the power curve more visible (Figures 24 and 25).
