No, the visualization is adjusted such that it always shows at least one female->female connection, and one male->male connection.

So it might very well be the case that there are a lot more heterosexual female welders than homosexual female welders, it's just that there are so many male welders that their connections dominate the top five.

Oh, I didn't realize the visualization was adjusted like that. That makes more sense.
