Yeah, the bigger the star, the less efficacious the transit technique would be in finding planets, because the weaker would be the signal of the shadow of the planet next to the output of the star. That's why few have been found around stars much bigger than the sun.
The farther the planet is from the star, the Worse it is for transit because the larger the orbit compare to disk of the star, so the smaller the chances for any transit at all, and longer the period between any transit for rechecking observations. So also the less efficacious the transit method.
So transit method is best for detecting large planets orbiting in small orbits around small stars with stable light outputs. Hence the biase in that drawing.
