In this chapter, we learned about gauge, polar, and range charts. An extensive step-by-step demonstration showed how to plot a complex speedometer by utilizing most of the gauge options. We also demonstrated the differences between polar, column, and line charts with respect to principle and configuration. We used range charts to improve past chapter examples and study the subtle differences they insert into the chart. Finally, we explored how to define radial gradients by tweaking the options in stages.

In the next chapter, we will learn the structure of a bubble chart by recreating it from an online sport chart. Then, we will briefly discuss the properties of a box plot chart by transforming data from a spider chart, following with presenting the F1 race data with an error bar chart.
