<p class="short-description">The Structures_Graph class represents a graph data structure.</p>
<p class="description"><p>A Graph is a data structure composed by a set of nodes, connected by arcs. Graphs may either be directed or undirected. In a directed graph, arcs are directional, and can be traveled only one way. In an undirected graph, arcs are bidirectional, and can be traveled both ways.</p></p>
