I turned my GitHub year into a 3D solar system for my profile README

Description and use

A GitHub Action that generates a 3D solar system SVG from a user's yearly contributions, to be embedded in the profile README. It updates hourly and runs entirely within GitHub Actions.

Problem

GitHub's contribution graph is a grid of green squares that looks similar for everyone and tells little story.

Outcome

The profile README now displays a dynamic 3D solar system SVG that updates hourly, reflecting yearly contributions, busiest month, top repos, and day/night themes, without external rendering services.

Workflow

• Create a public profile repository named <username>/<username>
• Add a workflow file .github/workflows/git3d-universe.yml with the Git3D Universe action
• Set timezone in the workflow
• Run the workflow manually once to generate the SVG
• Add the SVG to the README with 
• The workflow runs hourly, commits changes only when the image changes

Evidence

Git3D Universe: a free GitHub Action that turns your year of contributions into a small 3D solar system, drawn as one self-contained SVG for your profile README.

Source

The workflow keeps the image up to date and commits it only when something changed.

Source
