This hypercube graph is an <a href="https://en.wikipedia.org/wiki/Projection_(linear_algebra)#Orthogonal_projections" class="extiw" title="en:Projection (linear algebra)">orthogonal projection</a>. This oriented projection shows columns of vertices positioned a vertex-edge-vertex distance from one vertex on the left to one vertex on the right, and edges attaching adjacent columns of vertices. The number of vertices in each column represents rows in <a href="https://en.wikipedia.org/wiki/Pascal%27s_triangle" class="extiw" title="en:Pascal's triangle">Pascal's triangle</a>, being 1:3:3:1 in the case of a 3-cube (cube).
