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.

SVG, HTML, and accessibility

Accessibility on the web strives to ensure that people with disabilities can access sites and applications. The general goal is to provide content that is served and structured in such a way that users with disabilities can access it directly or, if direct access isn't possible because of their disability (for example, audio content is needed for a hearing-impaired user), to provide properly structured alternative content that conveys the same information. This structured alternative content can then be accessed through Assistive Technology (AT). The most common example of AT is the screen reader. 

Screen readers exist for all platforms. Some free applications you can test with include the following:

  • NVDA (Windows)
  • Apple VoiceOver (OS X)
  • Orca (Linux)

In the case of SVG, a visual format, the focus is on providing, when it's appropriate, textual content that describes the image. 

As you're hopefully aware, HTML itself has tools and best practices for accessibility. In...
