The house of the dragon chart example is also themed explicitly according to the show. Unlike realistic pictures, the tree line uses animated cliparts similar to the real-time HOTD characters. The background is of a constant repetitive pattern. Besides that, the characters have medium opacity shapes, making them distinct. The whole series revolves around the main character Rhaneyra Targaryen. So, the tree line focuses on her and ends at that specific generation. There isn't much detail in the chart. The only thing available is the name of the member.
