Chapter 12. Data

Data visualization is one of the most active areas at the intersection of code and graphics and is also among the most popular uses of Processing. This chapter builds on what’s already been discussed about storing and loading data earlier in the book and introduces more features relevant to data sets that can be used for visualization.

There’s a wide range of software that can output standard visualizations like bar charts and scatter plots. However, writing code to create these visualizations from scratch provides more control over the output and encourages users to imagine, explore, and create more unique representations of data. For us, this is the point of learning to code using software like Processing, and we find it far ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.
