For pairwise coprime integers $(p,q,r)$, we define a Brieskorn homology 3-spheres by $\Sigma(p,q,r)=\{(z_1,z_2,z_3)\in\mathbb{C}^3 | z_1^p+z_2^q+z_3^r=0, |z_1|^2+|z_2|^2+|z_3|^2=1\}$.

I want to know any explicit Heegaard diagram of $\Sigma(p,q,r)$.

What I can find is Heegaard diagram of Szabo's lecture note (Diagram 2.7).

Are there any more?

Since any other Heegaard diagram can be obtained from this one by isotopy, handle slides and stabilization, you can draw many examples using those moves on the given diagram. – Pandora Mar 18 at 16:16
