  Here are some easy to use Java applets for effective visual presentation of data. They say pictures are worth a thousand words. When the pictures are interactive, they add another thousand ! There are two applets for 'Drill Down' presentation of data. In the simple version data comes from the webpage itself. In the advanced version data is from files, prepared from RDBMS tables--useful in the context of data mining and data warehousing.
Another fine applet is for presenting time dependent data- Time Line Chart also known as Gantt Chart
