## Adding data to the graph
 
```js
Button("Adding to the graph", async () => {
  const graph = await gxr().graph();
  graph.clear();
  // Add node
  graph.add("A");
  // Add node with options
  graph.add("B", { category: "B", properties: { age: "32" } });
  // Add edge
  graph.add("A", "B");
  // Add edge chain
  graph.add("X", "Y", "Z");
  // Add edge with options
  graph.add("B", "C", { relationship: "BC", properties: { since: 2010 } });
  // Add nodes
  graph.add(["D", "E", "F"]);
  // Add nodes with options
  graph.add(["G", "H", "I"], { category: "GHI" });
  // Add node with properties
  graph.add({ age: "23" });
  // Add node with options
  graph.add({ id: "Person23", category: "Person", properties: { age: "23" } });
  graph.add([{ id: "J", category: "J", properties: { age: 113 } }]);
  // Add nodes with properties
  graph.add([
    { age: Math.random() * 100 },
    { age: Math.random() * 100 },
    { age: Math.random() * 100 },
  ]);
  // Add nodes with properties and options
  graph.add(
    [
      { age: Math.random() * 100 },
      { age: Math.random() * 100 },
      { age: Math.random() * 100 },
    ],
    { category: "Person" }
  );
  // Add edges with options
  graph.add([
    { sourceId: "D", targetId: "E", relationship: "PRECEDES" },
    { sourceId: "E", targetId: "F", relationship: "PRECEDES" },
  ]);
  console.log("Node count is correct", graph.nodes().length() === 21);
  console.log("Edge count is correct", graph.edges().length() === 6);
