Artwork from activity graph?

Hello,
I did not find any tools which could allow me to create an artwork from my activity graph like you can find for GitHub (ie https://codeprints.dev/ or https://getoss.art/)

I’m leaving my current company after 15 years of coding and I would love to be able to keep a memory like that .

Do you know if there some tool ou there which could help me ?
At least does gitlab have the API for it so I can do something my self ?

Thanks for your help
