gitartwork on user's contribution graph, make a SVG image of it and finally push it back to your repository.

An example result:

1. Ensure that under Settings > Actions > General > Workflow permissions, the "Read and write permissions" is set!

2. Copy the workflow code into a .github/workflows/gitartwork.yml file in your repository.

    name: gitartwork from a contribution graph
    on: 
      push:
    jobs:
      build:
        name: Make gitartwork SVG
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v3
          - uses: jasineri/gitartwork@v1
            with:
               # Use this username's contribution graph  
               user_name: jasineri
               # Text on contribution graph 
               text: JASINERI
          - uses: jasineri/simple-push-action@v1
   

3. A few moments later it will generate gitartwork.svg image in your repository, so then you can include it in your README.md like ![gitartwork](gitartwork.svg)

4. Have fun :)

1. If your gitartwork's image is missing and the action workflow ends with an error message stating "Permission to ... denied to github-actions[bot]", check the workflow permissions settings (see "Usage" above).

Still in progress...
