D3.js 5.0 is out
The sad state of affairs is that while D3 is brilliant in terms of API design, it is fairly low level, so few people use it directly. I've been using tools based on D3.js (like C3, NVD3) and it's been a joy.<p>However, last time I checked (~mid 2017), most of these hadn't migrated to D3 v4, so I'm not sure how fast v5 adoption will be. Maybe some will skip v4 altogether and go directly to v5?<p>At this point, I'm not sure which wrapper to use, because I don't want to get stuck with v3.
