About metrics
Metrics is an infographics generator for GitHub accounts, published under the MIT license and written in JavaScript. It lives in the GitHub ecosystem as a GitHub Action and as a hosted web service, and it produces statistics about a user, an organization, or a repository. The output is rendered as SVG, Markdown, PDF, or JSON, which means the same generated figures can be embedded in a profile readme, attached to a blog post, or consumed by another tool.
