In this chapter, we learned the very basics of Ext JS, which is a framework for building Rich Internet Applications (RIAs). We looked at a quick introduction of a dozen Ext JS components that are likely to be used with the Highcharts extension for Ext JS. Then, we explored how to create a Highcharts component from an existing Highcharts configuration in a step-by-step approach. We looked into the small set of APIs that are provided by the extension module and built a simple application with network usage data. Finally, we took a brief look at Highcharts and Ext JS applied to a commercial network profiling application.

In the next chapter, we will explore how to run Highcharts on the server side.
