A graph is composed of nodes connected by relationships. The document provides steps to create a graph in Neo4j: 1) Create a node for yourself with the label "Person" and name property. 2) Match the node for yourself and create a "LIKE" relationship to a new "Database" node for Neo4j. 3) Match the node for yourself and loop through an array of names to create additional "Person" nodes connected as friends.
