Introduction: Data Manipulation and Preparation

We saw that preparing data can take much more mental effort and code than the process of creating charts. Or, to put it differently, if we invest a good amount of time in preparing our data and making certain decisions about how and what we intend to do with it, the process of visualization can be made much easier. So far, we have used a small part of our dataset and didn’t make any changes to its shape or format. And when making our charts, we followed the approach of building them from scratch by creating a figure and then adding different layers and options for traces, titles, and so on.
