A subgraph is a new graph formed using a selection of vertices and edges from a larger original graph. A spanning tree for a graph is a subgraph which is a tree and which connects every vertex of the original graph. So, when given a graph, we will find a spanning tree by selecting some, but not all, of the original edges.
