You want to show the data as a result on a web page? Yeah, Applets are a possibility, but you might find a better solution first...
If you can show the results as a sinmple column graph, you can have each as a 1x1 pixel gif and stretch to size (eg img src="red.gif" height="10" width="100") and change the width value for each. This is a VERY light solution.
You could also have a Servlet output a dynamic image of the graph you desire. This requires more work from the server, but I still prefer it over Applets and the troubles you'll inherit...
Another option is the bunch of 3rd party apps available to do the graphics for you, not that I can think of any.

One I've heard of (but have not used personally) is KavaChart.

I asked this very same question in this forum about a month ago. I had started to code my own servlet when I ran into a much easier way. If you have sas, there is a new option in version 8 that creates an applet from your data, in my case db2. Once created you can then click on the applet and change the graph type from a bar, to a pie graph, to a line graph, change colors, backgrounds, shapes, connectors, etc.
My manager needed 89 graphs in a hurry and this made it a snap to do in a very short time.
