I don't have an ada example, but you can do all the graph drawing with
standard javascript so that your ada code only needs to generates a
javascript call.

An example that uses tables and stretched bitmaps to draw histograms is
at

Click on any of the "histogram" links.  You're welcome to use the
javascript graphing routines you'll find in the listing of the left
hand frame.

If you need a line graph, you can use the same approach with the
javascript graphics library at

See the "function plotter" link for example.  I have used this
successfully on several small projects.  Again, your ada has little to
do.  Just set up calls to javascript routines.
