graphviz.sources.Source at 0x1b7181719a0

`graphviz.sources.Source` is a class from the Graphviz Python library used to represent and generate source code for Graphviz graphs. It is typically used in conjunction with the `graphviz.Digraph` class to create and render graphs in various formats.

Here is an example of using `graphviz.Digraph` and `graphviz.sources.Source` to create and render a simple directed graph:

from graphviz import Digraph, Source

# create a new directed graph
dot = Digraph()

# add some nodes and edges
dot.node('A')
dot.node('B')
dot.node('C')
dot.edge('A', 'B')
dot.edge('B', 'C')

# render the graph as a PNG image
dot.format = 'png'
dot.render('example')

# generate the source code for the graph
src = Source(dot.source)

# print the source code
print(src)

The output of the above code would be the source code for the graph in a Graphviz DOT file format. It can be used to render the graph in other formats, such as PDF or SVG, by using the `dot.render` method with the appropriate file extension.
