Certainly! Graphviz is a powerful tool for creating and visualizing graphs and networks. In this tutorial, we'll focus on creating edges with record-style labels using Graphviz in Python with the graphviz library.
Make sure you have Graphviz installed on your system. You can download it from the official website: Graphviz Download.
Also, you need to have the graphviz Python package installed. You can install it using pip:
Import the required module:
Create a Graph:
This creates a new directed graph named 'example_graph' and sets the output format to PNG. You can choose other formats like PDF, SVG, etc.
Add Nodes to the Graph:
Here, we're adding three nodes (A, B, and C) with different shapes. You can customize the node shapes as needed.
Create Edges with Record Labels:
The label attribute in the edge method allows you to specify a record-style label for the edge. The syntax {} is used to define a record, and you can include multiple fields separated by a vertical bar (|).
Render and Save the Graph:
The render method generates the graph and saves it to a file. The cleanup=True parameter removes the intermediate DOT file.
View the Generated Graph:
Open the generated PNG file ('output_graph.png' in this case) to view the graph with record-style labeled edges.
This example creates a graph with three nodes connected by edges, and each edge has a record-style label. Adjust the node shapes, labels, and other attributes as needed for your specific use case.
Remember to replace 'output_graph' with your desired output filename and adjust the graph attributes according to your requirements. Experiment with different shapes, styles, and labels to create visually appealing graphs.

Graphviz is a powerful tool for creating and visualizing graphs and networks. In this tutorial, we will explore how to add edge labels to records in Graphviz using Python with the gv library. Edge labels provide additional information about the relationships between nodes in a graph, making the visualization more informative.
Make sure you have Graphviz and the gv Python library installed. You can install gv using the following command:
Additionally, ensure that Graphviz is installed on your system. You can download it from the official website: https://graphviz.gitlab.io/download/
Let's start by creating a simple graph using Graphviz. We will then add records and edge labels to visualize relationships between nodes.
