How does one “join” two graphs in graph theory?
$begingroup$
I am asked to find the join of two graphs in graph theory. But I cannot find the exact definition! I know that in lattice theory, we join every vertex of a graph to every vertex of another graph to find the join of graphs. Any expert advice is welcome.

perhaps providing the actual question would be helpful. Literally, the join is the "graph with all the edges that connect the vertices of the first graph with the vertices of the second graph."

Let me know that when we draw join of two graphs, is that I should join every vertex of graph1 to every vertex of graph 2 by an edge?

The join of two graphs $G_1$ and $G_2$ , denoted by $G_1nabla G_2 $, is a
graph obtained from $G_1$ and $G_2$ by joining each vertex of $G_1$ to all vertices of $G_2$ . After joining the two graph the resultant graph will be of diameter at most 2.
