:clipboard: **Description**

[Altmetrics](https://www.altmetric.com/) - impact tracking of publications, preprints, etc.

Altmetrics badges show the impact of an associated DOI.

:microphone: **Motivation**

I maintain lists of scientific papers, such as [HiC tools](https://github.com/mdozmorov/HiC_tools). Knowing which paper is more impactful (from Altmetrics badges) will be immensely helpful to prioritize one's time.

Start with Altmetric's examples and embedding API documentation linked in the issue, focusing on how an associated DOI is identified and which impact data can be displayed. Done means Shields provides an Altmetrics badge that represents the impact of a publication, preprint, or other DOI-associated work.
