Hi @jcouyang ,

Good job on the script, it's working smoothly.

You can try this reliable github API to retrive SVG data which would make the script slightly more readable.

FYI, here's my implement with it.

Edit: Provide git blame against the API.

It's well.I will take it for my blog home page.Thanks!!!
