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.

More on basic shapes

Now that you've learned about path, let's take a look at some more straightforward parts of the SVG universe and let's examine some more basic shapes. You've already learned about circle and rect. Let's take a look at a few more basic shapes.

The line element

The path element allows you to draw anything you can imagine using a long series of instructions. Thankfully, there are many convenient elements that define common shapes that are a lot easier to work with than the path element. The first of these that you'll learn about is the line element.

The following example draws a grid on a 500 by 500 square. The line elements in use here take five arguments: x1y1, x2y2, and a stroke. The x and y coordinates indicate the beginning (x1y1) and ending points (x2, y2) of the line. This SVG document draws a grid 100 pixels on each side in a 500 pixel square:

    <svg version="1.1" xmlns="" 
        width="500" height="500" viewBox="500 500 0 0"&gt...
