Hi,

I am working on a project where we will not be able to avoid having to
join 2 datasets with duplicate keys, just because of the nature of the
data that we are working with.

In a relational scenario I could easily deal with this with a full
join that results in a Cartesian product, but I don't see what my
possible options are with the Google Visualization API.

>From the documentation:

"Only dt1, the left-hand table, can include duplicate keys; keys in
dt2 must be unique." 
http://code.google.com/apis/chart/interactive/docs/reference.html#google_visualization_data_join

So my question is, in situations where the keys in dt2 are not unique,
how could I handle the join?

Please help - thanks!
