That’s literally what a neural network is… It’s a graph, a bunch of nodes and the edges that connect them, and weights on those edges. It’s not three dimensional, it’s n-dimensional, where n is based on the size of the network

Here’s a tool that visualizes it

We can click on one of these points (“iceland”) to see its nearest neighbors in the high-dimensional space (mostly other countries!) as well as other points that belong to the same cluster (Cluster 18 is this red cluster).
