In this chapter, we discussed how to create a custom spacefilling chart where we created a series to create a periodic table and used that series with Sencha's spacefilling chart. We also discussed how to handle changing store data, styling sprites, and scaling up/down different dimensions. The implementation demonstrated Sencha Charts' important classes, their responsibilities, interactions, and how you can create a custom chart.

Now that we are done with creating different types of custom charts, in the next chapter, we will see how we can style and theme the charts.
