While only a few of the book's readers will need this chapter, it is a welcome addition none the less, extending the power and range of the Processing environment.
It is important to note that this book ramps up the requirement for technical ability and understanding quite quickly. The book itself admits that without a prior background in programming Chapters Five onwards will "quickly become more difficult". That said, it seems the author makes some attempts to accommodate varying degrees of programming knowledge throughout the text.
However, these attempts sometimes lead to either frustration or confusion. Frustration because there might be an explanation of a programming concept that seems obvious to a programmer Objects for example , and confusion because the explanation does not seem detailed enough for the beginner. The same can be said about the design and visualisation aspects of the text which sometimes left me, a beginner in the field, confused.
I wondered if the same explanations would perhaps seem obvious to a designer. It's a difficult ground for an author, but I think deciding firmly on a level and audience for the text would help clarify the writing, if limit the readership.
To conclude, Visualising Data is a useful publication. Yes, it can be quite dry at times, but good data is needed for good visualisation and good data is a dry subject. Yes, it can be quite wordy at times, though that may be my prejudice against wordy text books.
Yes, it sometimes tries to walk a middle ground of technical experience, which will leave beginners bemused and old lags bored, but, I suspect, outside computer science and design are large numbers of people who really are in this middle ground. Finally, do not be misled by the title. Visualising Data focuses mainly on Processing and how to use it to visualise data.
In this it is successful, and some general principles can be picked up along the way.
But I imagine there are better books indeed a couple are listed in the work's bibliography that explore data visualisation in general. So if you want an introduction to the subject, you would probably be best starting elsewhere, before returning to this book for a neat way to express your creative ideas.
It can be found at site and elsewhere. The book covers the data visualization process Chapter 1 , and a couple projects you'll find on this site, such as Salary vs. More about the book can be found in the writing section of the site. Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production.

Two from October Illustration comparing DNA of Humans vs. Chimps , and a cover for Nature , celebrating the first phase of the HapMap project. From October , an update to disarticulate for the Cooper-Hewitt. December work: Sketches for an illustration of the Enron email data set. Old work: Program elements in Processing are fairly simple, regardless of which language you're learning to program in.
If you're familiar with Python, it's best to forget that Processing has anything to do with it for a while, until you get the hang of how the API works. For this reason, Processing is free to download, free to use, and open source. But projects developed using the Processing environment and core libraries can be used for any purpose.
GCC and its associated libraries e. However, programs created with GCC examples too numerous to mention are not themselves required to be open source. This is the software that runs when you double-click the Processing icon.
The Python Mode add-on, which makes it possible to write programs in Python that look and behave like Processing programs and have access the Processing API. Are we talking about the API, the language, the development environment, or the web site? We'll be careful in this text when referring to each. Sketching with Processing A Processing program is called a sketch.
The idea is to make programming feel more like scripting, and adopt the process of scripting to quickly write code. Sketches are stored in the sketchbook, a folder that's used as the default location for saving all of your projects. Advanced programmers need not use the PDE, and may instead choose to use its libraries with the Python environment of choice.
However, if you're just getting started, it's recommended that you use the PDE for your first few projects to gain familiarity with the way things are done. To better address our target audience, the conceptual model how programs work, how interfaces are built, and how files are handled is somewhat different from other programming environments.
Hello world The Processing equivalent of a "Hello World" program is simply to draw a line: line 15, 25, 70, 90 Enter this example and press the Run button, which is an icon that looks like the Play button from any audio or video device. Your code will appear in a new window, with a gray background and a black line from coordinate 15, 25 to 70, The 0, 0 coordinate is the upper left-hand corner of the display window.
Building on this program to change the size of the display window and set the background color, type in the code below: size , background , 64, 0 stroke line , 25, , This version sets the window size to x pixels, sets the background to an orange-red, and draws the line in white, by setting the stroke color to By default, colors are specified in the range 0 to Like all Processing functions that affect drawing properties, the fill and stroke colors affect all geometry drawn to the screen until the next fill and stroke functions.
Hello mouse A program written as a list of statements like the previous examples is called a static sketch. In a static sketch, a series of functions are used to perform tasks or create a single image without any animation or interaction. Interactive programs are drawn as a series of frames, which you can create by adding functions titled setup and draw as shown in the code below.
These are built-in functions that are called automatically.
As such, setup can be used for any initialization; in this case, setting the screen size, making the background orange, and setting the stroke color to white. The draw block is used to handle animation.
The size function must always be the first line inside setup. Because the background function is used only once, the screen will fill with lines as the mouse is moved. To draw just a single line that follows the mouse, move the background function to the draw function, which will clear the display window filling it with orange each time draw runs.
For instance, a static program might start, draw a page to a PDF file, and exit. Most programs will use the setup and draw blocks. More advanced mouse handling can also be introduced; for instance, the mousePressed function will be called whenever the mouse is pressed.Online "data science" talk, more details here.
You can also specify your own name and file type for the file to be saved with a function like: saveFrame "output. This book teaches you: The seven stages of visualizing data -- acquire, parse, filter, mine, represent, refine, and interact How all data problems begin with a question and end with a narrative construct that provides a clear answer without extraneous details Several example projects with the code to make them work Positive and negative points of each representation discussed.
The focus is on customization so that each one best suits what you want to convey about your data set The book does not provide ready-made "visualizations" that can be plugged into any data set. Lecture with Casey Reas at Princeton University video.
Several core libraries come with Processing. From October , an update to disarticulate for the Cooper-Hewitt. Old work:
