With that finished, this chapter comes to a close. In this chapter, we covered the remainder of the charts of the pygal library, features, and proper uses of more advanced charts and very complex datasets. At this point, consider building your own charts with your own data. Experiment and play with the results; the more you play with the library, the better your understanding of how you should structure data. In the next chapter, we will start learning about pygal themes, optional features, and customizations.
