What's the best way to represent 3 variables (with 2 related to one) visually?

[Qacer]

I want to show that for certain people attraction is based on two things: brains and beauty. Attraction is high when both are high. Attraction is also high when either one is high. Attraction is low when both are low.

Any ideas on how to visualize this so the relationship is easily understood?

Thanks!

A hot smart chick and a hot chick equals boner?

I'd google image search some examples for you but I'm at "work".

Edit: The above is from a male perspective. For the female perspective I have mapped out for you the simple relationship between brains and beauty and their effect on attraction. The red dots represent high or low levels of brains, beauty, and attraction, the blue dot represents money, the white dots represent manlets.

I have no idea about this kind of stuff. But Venn Diagram popped into my head for some reason:

IV = Attraction
DV1 = Brains
DV2 = Beauty

Not to make fun but, well, I sure hope you're good lookin.

Use a contour plot. I'm trying to make a demo in Excel but Excel sucks dog's balls for contouring data.

sounds like you could adapt this one

Use a graph with 3 axis. x and y can be the dependent variables and z the dependent. To keep it 2D, you can have x and z on the plot and then different lines showing varying y. Example:

One of the most scientifically accurate graphs I have ever seen.
