NetlistSVG is great yeah. We had a play with it. We had a visualizer in the compiler early on in the compiler implemented with JointJS. But it was a pain to maintain and difficult to get value out of.

I'm sure we will have some flavor of a visualizer in the compiler one day. But outputting a "normal" schematic doesn't seem like it's the right approach. We might actually end up with a bunch of different ways to "visualize" your circuit, each one optimized for a specific thing you are trying to achieve.
