Как я могу создать стилизованную диаграмму деревьев? ⇐ Python

[Anonymous]

Я делал дерево сражающихся в братстве биг и литт, и искал способ автоматизировать его для изменений, когда присоединяются все больше людей. Имена и годы каждого, большие и маленькие, находятся в электронной таблице Excel. Что я могу использовать для эмуляции дизайна, который я сделал здесь? В частности, стиль ствола и способность к космическим узлам дальше в зависимости от их года. alt = "Дерево, которое я хочу подражать" src = "https://i.sstatic.net/8mjxj53t.png"/>
Я попытался использовать Anytree и Graphviz, но не мог Найдите способ эмулировать стебли или простое решение для расстояния на основе лет. ">
