Retrospectively looking at your Github contribution history.
The main reason that I've built this for is seeing that which years I've got something happened to my life. So, you might as well follow the turning points and contemplate about your life :)
It works with a username and years field that you are interested in. Just provide them as comma seperated.
Years can not be less than 2008 which is the Github's start date or greater than current year.
It just gives an svg image to put your profile readme or to see how amazing things you've done until now.
Feel free to open a PR to improve anything!
