+A bar chart is a way of showing data as bars.
+
+It is sometimes used to show trend data, and the comparison of multiple data sets side by side.
+
+##### Example
+
+    <chart-horizontal-bar data="[[data]]"></chart-horizontal-bar>
+
+    ...
+
+    this.data = {
+      labels: ["January", "February", "March", "April", "May", "June", "July"],
+      datasets: [
+        {
+          label: "My First dataset",
+          backgroundColor: "rgba(220,220,220,0.2)",
+          borderColor: "rgba(220,220,220,1)",
+          borderWidth: 1,
+          data: [65, 59, 80, 81, 56, 55, 40]
+        },
+        {
+          label: "My Second dataset",
+          backgroundColor: "rgba(151,187,205,0.2)",
+          borderColor: "rgba(151,187,205,1)",
+          borderWidth: 1,
+          data: [28, 48, 40, 19, 86, 27, 90]
+        }
