I'm surprised by the amount of skepticism I'm noticing here. I have been following Suhail's work on Mighty for a few months and I was very much looking forward to it.

One use case that where I think this would make my life easier is in the big-data / ML space where I'm trying to visualize large quantities of data. JS, WebGL and other supporting tools are all available today, but it's quite painful to load a graph visualization with 1M nodes and make it responsive without spending a lot of time optimizing the JS code. As a data scientist when I'm simply hacking stuff and want a quick prototype it's nearly impossible.

Graphistry [https://www.graphistry.com/] has a decent setup for graphs viz, but it didn't quite fit my needs. I've also tried JS running on a large machine (with GPU) and VNCed to it. That experience was quite poor.
