@brundabharadwaj I'm not sure if I understand your request correctly. Do you want us to display more information about the ranks? Do you mean the explanation in the readme but then displayed when hovering the rank circle (see https://stackoverflow.com/questions/41768657/display-text-over-svg-element-on-hover).
Note Available ranks are S+ (top 1%), S (top 25%), A++ (top 45%), A+ (top 60%), and B+ (everyone). The values are calculated by using the cumulative distribution function using commits, contributions, issues, stars, pull requests, followers, and owned repositories. The implementation can be investigated at src/calculateRank.js.
Available ranks are S+ (top 1%), S (top 25%), A++ (top 45%), A+ (top 60%), and B+ (everyone). --> Exactly! as you have explained over here! @rickstaa
Closing this as hovers are currently impossible inside GitHub READMEs (see https://github.com/anuraghazra/github-readme-stats/issues/2455#issuecomment-1400578874).
