 Open the “Get the Code” github URL listed below, mark or Ctrl-A to select all of the text, and copy the text for the flow to your Clipboard. Recall from a previous section, click on the Node-RED Menu, then Import, then Clipboard. Paste the text of the flow into the Import nodes dialog and press the red Import button. Finally, click on the red **Deploy** button in the upper right corner.

 - You might have noticed that the flow import in the prior step actually created three tabs.  These are called Node-RED flows.
 - The **Chart Intro** flow introduces you to the various Node-RED Dashboard Chart types that are available.  You can create Line charts, various Pie chart styles – Pie, Donut, Polar Area, Radar - and vertical and horizontal Bar charts.

 - The Node-RED flow is not nearly as interesting as the charts that it renders.  To launch the Node-RED Dashboard, in the Node-RED sidebar, turn to the **dashboard** tab and click on the **Launch** button (1) [See two pictures above].

 The next Node-RED flow - **Dashboard Intro** - uses a variety of UI widgets to display data in the Node-RED Dashboard.  There is a Switch node that turns On/Off a random number generator function node.  The simple random numbers are sent to a line Chart node, a Gauge node, a Slider node, a Text node and, if the number exceeds a threshold, will display an alert notification message.

 Often IoT devices and sensors are deployed so that alerts can be triggered when the real time sensor data exceeds a threshold value.  In this last Step, the flow checks the temperature values and, if the temperature exceeds the threshold, triggers a Node-RED Dashboard notification.
