Basic Flowchart
from graphviz import Digraph
# Create flowchart
dot = Digraph()
dot.attr(rankdir='TB')
# Add nodes
dot.node('A', 'Start', shape='ellipse', style='filled', fillcolor='lightblue')

dot.node('D', 'End', shape='ellipse', style='filled', fillcolor='lightcoral')
# Add edges
dot.edge('A', 'B')
dot.edge('B', 'C', label='Yes')
dot.edge('B', 'D', label='No')
dot.edge('C', 'D')
