I am in the middle of putting together a data analysis
application. The users are beginning to ask if they
can have graphic displays (bar/pie charts) of selected
data.

My first thought was to use M$ Graph. Is there a better
approach? Perhaps Excel, but I'm not sure all the
users have Excel on their PCs. Of course, the queries
will be dynamic in nature (won't know what will be
selected until they do it) so I can't use static images.

Your ideas and suggestions are welcome.
