Here we end our journey exploring pie and polar charts and their variants. We learned to plot basic pie charts, sliced them off, and configured them for the drilldown feature. We used the 3D module to create a 3D pie chart and then created a single chart with two pie series side by side. We also learned to convert a pie chart into a donut chart and then combined pie charts with other different types of charts. Then we started creating polar charts; by tweaking their configuration options, we created several other chart types such as wind rose and spider web.

We have almost completed exploring major chart types that Highcharts provides. In the next chapter, we will look at some other chart types, including gauges, pyramid charts, funnel charts, and heat maps.
