# GvGen — Generate clear Graphviz Graphs which can be edited manually later on.

License: permissive · Maintenance: abandoned · Downloads: 250.0K/mo

## What it is and what it does

GvGen is a Python wrapper around Graphviz's dot format that lets you build graphs programmatically instead of writing dot syntax by hand. You create nodes and clusters, link them together, apply styles and properties, and generate dot output ready for Graphviz to render. It handles common tasks like node naming, edge properties, style application, and even legends.

The package is useful when you need to generate graph visualizations from code—for example, building dependency diagrams, organizational charts, or network topologies dynamically. It abstracts away dot syntax details and provides a Python API for graph construction. However, it has been unmaintained since 2020, so there are no recent updates or bug fixes.

Use it for:

- Generate organizational or family tree diagrams programmatically with styled nodes and clusters.
- Build network topology or system architecture diagrams from code-driven data.
- Create dependency graphs or flowcharts where structure is computed at runtime.
- Visualize relationships in data by converting Python objects into styled graph nodes and edges.
- Generate documentation diagrams that need to be updated when code or configuration changes.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

GvGen generates Graphviz dot files programmatically, letting you build directed graphs with nodes, clusters, edges, and custom styling in Python without writing dot syntax directly.

Yes, if you need to generate Graphviz diagrams from Python and don't require active maintenance. The package is stable and has no known vulnerabilities, but be aware it is abandoned and will not receive updates. It is suitable for one-off scripts or projects where you control the Python version and can work around any issues yourself.

## Install

pip install gvgen
uv add gvgen
poetry add gvgen

## Installing GvGen

Before you install: Installation is straightforward with no runtime dependencies. However, the package has been abandoned since its last release on 2020-02-12 and receives no maintenance, so expect no bug fixes or updates.

License in practice: Licensed under MIT (permissive), so you can use, modify, and distribute it freely with minimal restrictions.

Quickstart:

pip install GvGen

from gvgen import GvGen

graph = GvGen()
parents = graph.newItem("Parents")
bob = graph.newItem("Bob", parents)
alice = graph.newItem("Alice", parents)
graph.dot()

Graphviz itself must be installed separately on your system to render the generated dot files into images (e.g., via `dot -Tpng file.dot`).

Verify before relying:

- Whether the package works correctly with modern Python 3 versions beyond what the classifier claims.
- Whether any edge cases in graph generation have been discovered since abandonment in 2020.
