Since 2.17.0, window.d3 is exported with internal 3.8.0 version preventing loading of external d3 library

[lucasnetau]

Versions 2.17.0 to 2.18.1 (since change to webpack), window.d3 is defined to the Plotly packaged D3 3.8.0 version. This prevents loading a newer version of D3.

A newer version is needed since Plotly 2.0.0 to access d3.csv/json and also d3 colours (eg d3.schemeCategory10)

• Result with version 2.16.5 and prior https://jsfiddle.net/ga9rskdj/1/
• Failure with version 2.17.0 and later https://jsfiddle.net/f15jursm/

Workaround is to set window.d3 = undefined after loading Plotly.js and then including external D3

Thanks for the report.

Among all the keys on window, d3 is the only module somehow exported!
This suggests we should fix the problem at @plotly/d3 level.
