Plotly vs D3.js

Greetings - I know this question may be a little off considering I’m asking it in a PLOTLY FORUM, however, I’m relatively new to the field of data visualization and I was wondering how plotly fared against D3 in terms of capability, function, etc. Is D3 more capable than plotly in its ability to draw illustrations / charts / etc? and if so, how?

is a pretty good starting piece on the subject.
