In this chapter, you learned the essentials about absolute and relative units to define lengths in a browser. We remember that the
rem unit plays an important role because it allows a layout to adapt when a user increases the font size of the website.
Then, you learned about how to use relative units, viewports, and resize events to adapt the chart size and the data resolution according to the current container size.
In the next chapter, we will continue with implementing responsive charts and take a closer look at creating responsive interactions for all the types of devices and screen resolutions.
