Thanks your reply.
The case looks a little different, for dot-chart, it knows the
positions so it could create image map based on the dot position. But
for the map chart, I don't have the boundary data, or I am just a
little "lazy" to create one. I am wondering whether google or some
other third party created those country/state boundary data already.
Thanks again .

In addition to the data point tooltips, it also highlights a grid row
when a data point is clicked.

Say in US map, user click on one state, say, "Texas", some event will
be triggered with "Texas" information. I guess it would need imagemap
along with the border info of each country and each state. Some
concern is that since the since of map chart could be various, now
sure whether those border info would be adjusted accordinately.
