{rmpk} has early support for set-based formulation of constraints. The general, abstract idea is that you can write a constraint of an optimization problem as f(x) \in some_set (e.g. x_1 + x_2 == 4 or x_{1:3} as SOS1). Similar to MathOptInterface.jl #orms #rstats

The question I get most often is "How do I learn D3?" From now on I think I'll just point everyone to this post from @didoesdigital, it's by far the best and most comprehensive post I've ever read on the subject. medium.com/@didoesdigital
