Mastering SVG

By: Rob Larsen

Overview of this book

SVG is the most powerful image format in use on the web. In addition to producing resolution-independent images for today's multi-device world, SVG allows you to create animations and visualizations to add to your sites and applications. The simplicity of cross-platform markup, mixed with familiar modern web languages, such as CSS and JavaScript, creates a winning combination for designers and developers alike. In this book, you will learn how to author an SVG document using common SVG features, such as elements and attributes, and serve SVG on the web using simple configuration tips for common web servers. You will also use SVG elements and images in HTML documents. Further, you will use SVG images for a variety of common tasks, such as manipulating SVG elements, adding animations using CSS, mastering the basic JavaScript SVG (API) using Document Object Model (DOM) methods, and interfacing SVG with common libraries and frameworks, such as React, jQuery, and Angular. You will then build an understanding of the Snap.svg and SVG.js APIs, along with the basics of D3, and take a look at how to implement interesting visualizations using the library. By the end of the book, you will have mastered creating animations with SVG.

Transformations


Transformations in SVG allow you to manipulate an SVG element in a variety of ways, including scaling, rotating, skewing, and translating (which looks like moving the element, but isn't exactly that). Using transformations allows you to manipulate the SVG without changing its intrinsic values (for example, height, width, x, and y) which is important when you're manipulating elements in a dynamic way.

This section will introduce you to the common transformation functions one by one, with examples of each. 

translate

The translate transform moves the SVG element by the specified x and y coordinates. A translation changes the origin of the element's coordinate system.

The y coordinate is an optional argument and is assumed to be equivalent to the x argument if it's not provided.

The following sample shows three equivalent circles. The first circle is not transformed in any way. The second is transformed with a single argument (10), which moves it by 10 on the x axis and 10 on the...
