 Very simple example:
-<pre>
-// init example series data

+```java
+// Init example series data
 GraphViewSeries exampleSeries = new GraphViewSeries(new GraphViewData[] {
-	      new GraphViewData(1, 2.0d)
-	      , new GraphViewData(2, 1.5d)
-	      , new GraphViewData(3, 2.5d)
-	      , new GraphViewData(4, 1.0d)
+	      new GraphViewData(1, 2.0d),
+	      new GraphViewData(2, 1.5d),
+	      new GraphViewData(3, 2.5d),
+	      new GraphViewData(4, 1.0d)
 });
 
 GraphView graphView = new LineGraphView(
-      this // context
-      , "GraphViewDemo" // heading
+      this, // context
+      "GraphViewDemo" // heading
 );
 graphView.addSeries(exampleSeries); // data
 
 LinearLayout layout = (LinearLayout) findViewById(R.id.layout);
