I have published a Chrome Extension called Beautiful GitHub. I’m sure if you are a regular GitHub user you would have noticed the Halloween themed contribution graph. I liked it and thought how about having such beautiful graph with different colors all the time and so build this extension.
You can install it from Chrome store here - https://goo.gl/GY4kyo
Would love to hear your feedback.
You can also check out the source code on GitHub - https://github.com/vatz88/Beautiful-GitHub
Here’s a GIF which shows graphs of different colors the extension will show randomly.
