comment Can Mathematica use a MySQL ODBC connector?
Thanks Albert. You're right the documentation does say that (the code that I posted came from the same page). I'll try to get the error message from the user and post it. I want to use a DSN instead of typing in the server location, that's why I'm not using the mysql-jdbc driver.

@Andry I don't have any first hand experience with C/Mathematica links but it looks like you call it more like the putFunction method call in the Java. Have a look at this; reference.wolfram.com/mathematica/tutorial/…

Not a problem jmlopez. The standard Wolfram example is a good one I think.

comment How do I create an ellipse bubble chart?
@Jonathan thanks for all your help. Ultimately your answer may be the best because with rcollyers answer you lose the tool tip which is a bit of a problem for me (even if I didn't say that in the question).

@JonathanShock unfortunately that doesn't seem to work. When I use datatoplot = {{1, 2, 0.5, 0.7}, {10, 5, 10, 0.2}} the ellipses appear in the right place but the width/height are clearly incorrect. This is a little confusing.

comment How do I create an ellipse bubble chart?
@Jonathan. I was just asking because if I plot datatoplot = {{1, 2, 3, 4}} with this method I get an ellipse that's 0.8 high and 0.4 wide. I would have expected to get width=3 and height=4. Is there something that I'm missing?

Indeed. What I hope to be able to do with this tool is to be able to see in 2d space whether various data points are distinct. I'd expect to see some overlap.

Does this solution mean I have to scale my data?

I'm getting a message "f is not a Graphics primitive or directive." in Mathematica 9.0.1.0

Thanks Jonathan. If at all possible I'd like the keep the bubble chart. I'm currently using a tool tip so when you place your mouse over the bubble a table appears showing the values (I left that bit out of the question because I didn't want to complicate things). The bubble chart also highlights the bubble you're mouse is over which looks nice.
