Although I’ve only been lurking here so far, I’ve learned a lot by reading previously answered questions. @etienne in particular seems to be very helpful and replies to nearly every thread. So I thought I’d make an account and give back to the community by demonstrating how to make Plotly data points draggable. I put up a demo at bl.ocks.org with a brief description of the trick I used to make it work, and the code is in this gist. Hope someone finds this useful!
