A method and apparatus for identifying a relative importance of words in a word cloud. A computer system identifies graphical features and locations for the words representing information in the word cloud based on a group of metrics for the information. The graphical features distinguish the words from each other based on a first number of first values for a first metric in the group of metrics. The locations of the words distinguish the words from each other based on a second number of second values for a second metric in the group of metrics. The word cloud is displayed on a display system using the graphical features and the locations for the words in the word cloud in graphical user interface, which enables identifying the relative importance of the words in the word cloud based on the group of metrics for the information represented by the words.
