Congrats, you’ve reached the end of this chapter! 🎉
You now know how to load, join, cache, explore, transform, summarize, filter, and export tabular data. You can also work with geospatial data, perform spatial joins, and prepare geographic datasets for analysis. Finally, you know how to turn your results into charts and maps with SDA and Observable Plot.
Now you are ready to tackle Wrangling Statistics Canada Census data 🇨🇦. You’ll put your tabular, geospatial, and visualization skills into practice with a large real-world dataset.
If you haven’t completed The one billion row challenge 😱 yet, this is also a great time to try it. It will test your ability to process and summarize a truly massive dataset efficiently.
Once you’ve completed both projects, move on to Chapter 4, Git & GitHub. You’ll learn to track changes to your code and collaborate on projects.
