      <p>We'll build a simple restaurant sales example, where the user will enter the items sold by a restaurant in a given week. This data will be submitted in a form to the server. We'll acquire this data and plot in on a chart. For the sake of simplicity, we wouldn't do any processing on this data. However, your real life applications might process data before presenting it on the chart. </p>
