Behaviors are not supported in d3 v4

Question

Trying to upgrade d3 in my project, but error prompted: Cannot read property 'drag' of undefined It's caused by using d3.behavior.drag()

Here is the document of Behaviors for V3 https://github.com/mbostock/d3/wiki/Behaviors

But it's seems it's not supported in v4 https://github.com/mbostock/d3/tree/4

It's that API in already in roadmap, or there is some better way to implement behavior now?

Answer 1

Answer it myself: https://github.com/mbostock/d3/issues/2461 It still on the way, will be there in a separate module.
