This house of the dragon treeline interface is same as typical organizational chart. The background is full white for simplicity. Three different color scheme circles have character cliparts and pictures in them. They help to judge whether the member belongs to House Targaryen or the other. Besides the curved connecting lines, there is a specific dotted line connection that shows 100 years gap in generation time. On top of all that, the chart also depicts in which generation two houses came together through marriage.
