D3 is very powerful and well-engineered, with well-considered abstractions that really do manage to cover virtually every imaginable visualization. But its user-facing API is hot garbage. It's actually impressive that they've managed to come up with such an confusing and hard to track API for concepts that are themselves not fundamentally confusing. But it is what it is, it's established, it's here, so you kind of just have to bite the bullet and push through.
