使用Python绘制的树木源码，主要原理为使用分形画树干、树枝，最终叶节点上画上绿色圆圈代表树叶。 -Drawn using the Python source tree, the main principles for the use of fractal art stem, branch, leaf nodes and draw the final green circles represent leaves.

对图的深度，广度遍历，关键路径算法，最短路径算法实现，求生成树的深度及叶子结点数-Depth, breadth traversal, critical path algorithm, the shortest path algorithm, find the depth of the spanning tree and leaf nodes
