<p>The Weighted Centroid is a java applet designed to display a circular graph based on word distribution data. The text is divided up into an arbitrary number of units, which are positioned around the circumference of the circle in a clockwise sequence. The more times a word appears in a particular text unit, the closer the word will be to that unit in the circle, and the more units it appears in, the closer it will appera to the centre.</p>
