Genetic correlation of various human qualities

What do the negative vs. positive correlations mean here? I mean, you can smoke more or less, so that's clearly a scalar variable, but how are, for example, "non IQ genes" a scalar variable that can have a positive or negative correlation with smoking?

I think, and I am no expert in this.. but a genetic correlation is between two traits.

Negative genetic correlation: if X increases then Y decreases

Positive genetic correlation: if X increases so does Y

I think each trait on the graph should be paired with educational attainment as a second trait.

So: GeneticCorrelation(Cigarettes, EDUCATION) -> Negative

GeneticCorrelation(Longevity, EDUCATION) -> Positive

My take is this: The chart shows the relationship between the genes responsible for higher education X and {insert trait} = Y, where X is further split into IQ and non-IQ..
