Dear All,

I know VERY little about programming, but have managed to set up a google 
wordtree chart using some of my own data.  I have significant amounts of 
data, and want to find some of the key words that come up frequently, but 
unfortunately the wordtree that is currently being output highlights "the" 
and "of" and commas. I am wondering if there is any way I can either limit 
it to nouns, verbs, adjectives and adverbs? Or, failing that, limit the 
root word to more than 3 characters? 

This is what I have.. 

var data = response.getDataTable();
var chart = new 
google.visualization.WordTree(document.getElementById('wordtree_basic'));
        chart.draw(data, options);;
}
        var options = {
          wordtree: {
            format: 'implicit',
            word: 'development',
            function strlen(minlength) {
            var minlength = 4; }

          }
        };


Thanks in advance,
Anneleis
