Drupal Releases Lifecycle Graph

This Python script generates a visual timeline of the maintenance and security lifecycle for recent Drupal versions (10.3 to 11.3) using color-coded horizontal bars.

• ✅ Green: The version is actively maintained.
• 🟡 Yellow: Security fixes only.
• 🔴 Red: The version is no longer supported.
• 📍 A vertical dotted line indicates today's date.
• ⏳ Versions are sorted chronologically (oldest at the top).
• ⚠️ Future dates are estimates and will be updated when official release/support dates are confirmed by the Drupal team.

📸 Output

The chart displays:

• The version number on the left, with a background color matching the current support level.
• A time-based X-axis labeled in French, showing the month and year.
• Faded bars for phases that are in the past, to visually distinguish historical from current/future periods.
• A legend in the top-right corner.

🖼️ An example of the final output is available at the root of the repository as graph_example.png.

🛠️ Requirements

Ensure Python and required libraries are installed.

Step-by-step installation on Ubuntu example:

# Install Python.
sudo apt update
sudo apt install python3
sudo apt install python3-pip
sudo apt install python3.12-venv

# Create and activate a virtual environment.
python3 -m venv .venv
source .venv/bin/activate

# Install required Python packages.
pip install matplotlib pandas

# Run the script.
python drupal_releases_graph.py

# Deactivate the virtual environment when done.
deactivate

🖼️ Output Behavior

By default, the script will open a preview window showing the generated chart.
This allows you to tweak the layout and manually export it if needed.

To automatically export the chart as a PNG without preview, edit the file:

• Comment out the preview line:

  plt.show()

• Uncomment the PNG export lines:

  plt.savefig("drupal_versions_lifecycle.png", dpi=300)
  print("✅ File saved: drupal_versions_lifecycle.png")

These lines are located near the end of the script (drupal_releases_graph.py, around line 137).

📂 Output File

When the preview is disabled, the chart will be saved as:

drupal_versions_lifecycle.png

in the same directory as the script.

📌 Notes

• This chart can help teams anticipate version transitions and end-of-life deadlines.
• If you'd like to generate an SVG version or change language settings, feel free to adapt the script.
