D3v3 in dependency tree

[ccancellieri]

Hi, thanks for your work.
I'm trying to use the latest version of your react-d3-basic library but I'm getting a conflict with D3 version
seems that you are getting d3v3 as transitive dependency for the react-d3-shape and this conflicts with other libraries using the correct d3v4 version.
$npm ls react-d3-basic
├─┬ react-d3-basic@1.6.11
│ └─┬ react-d3-shape@0.2.24
│ └── d3@3.5.17

Could you fix soon?
