Demo not working

[pwFoo]

Hi,
I get an error if I try to use the demo / sandbox links.

@antv/graphin has clearly introduced some breaking changes. Either roll back to older versions, or help out with a PR

Hi @lmangani
Sorry, I just clicked the links and thought error should be visible to each one uses the links.

So it's a graphin problem or wrong version used in your demo?

It's neither. This demo is 2 years old, and since then the graphin library must have introduced some breaking changes. I have no idea where, but it should be easy to fix. Feel free to submit a PR if you find the problem and want to share it with others. Thanks!
