graph-view.js uses d3 transition. this is a d3 v3 api.

react-digraph/src/components/graph-view.js

Line 800 in 0d950ea

.transition()

likely related to #71

I've checked and looks like the downgrade fixes this, but then I get d3.zoom is not a function, so it might not be a solution.

@vicapow Please provide an issue number with the PR and make sure to sign the CLA.

Alternatively, instead of downgrading d3 (which is not desirable), please create a PR which fixes the code. If the transition API needs to be used differently then please modify that part of the code. If you don't want to create a PR then please create an Issue with the bug described, any console messages or visual details, and reproduction steps listed. Thanks!

This is broken on master. I recommend landing this and upgrading d3 later. The issue number was provided above. #71

[NameFILIP]

to clarify, I haven't been able to verify if downgrading fixes the issue. I'd investigate more why exactly the error is happening

[ajbogh]

I'm going to close this PR as the CLA hasn't been signed and the bug is fixed in #74.
