Visual programming is still very much used today if we count Unreal Engine blueprints, Blender shader nodes, Unity shader graph, etc.

Have a look at SideFX Houdini - the whole environment is node based. Building models can take some getting used to, but it's really powerful.

SideFX and derivatire started out as one team at first then they split and touchdesigner was born. TD is a powerhouse. https://derivative.ca

Then there is https://cables.gl that is all web based and pretty neat to play around with.
