Have a look at the source before continuing. This demo – based on the original over at the official docs – shows a simple Pie Chart in action. It’s pretty simple to get up and running with Google Charts.

While the original version relied on images, the improved API now utilises the power of HTML5 and SVG to render a range of dynamic charts which are customisable and allow complex interactivity.īackwards compatible via VML for older versions of IE, charts will render well across a range of devices including iOS and Android phones. All in all, it’s an excellent choice for charting on the web. It’s extremely powerful and being Google, well supported and documented. Google maintains and develops a fully featured charting library called the Google Charts API. and it appears that Google agree with me! 02. Whilst there is a performance consideration associated with the DOM – especially when working with larger files – typically I feel SVG is a more suitable technology for creating charts on the web. This means that it maintains a DOM whose attributes can be read and dynamically updated via scripting at any point in the page’s lifecycle. Whilst not strictly part of the HTML5 spec, it offers several advantages over Canvas for charting on the web.Ĭhief amongst these is that SVG is vector based and is described using an XML-based syntax. Once it’s drawn it’s drawn.Īn alternative technology is SVG. With Canvas you can't attach event handlers or manipulated existing objects. While Canvas does an excellent job of rendering dynamic charts, its main drawback is that it is a pixel- based graphics API. My particular favourite is the Filament Group’s jQuery Visualize plug-in, which even harnesses the magic of Google’s excanvas.js script to ensure dynamic charts can be generated in browsers as far back as Internet Explorer 6. Some excellent canvas charting tools exist. This makes it useful for quickly generating chart visualisations from HTML tables and with clever scripting can even allow some basic interactivity.

Canvas is fast and unlike a static images can be dynamically redrawn in- page using scripting. According to the Mozilla Developer network, HTML5 canvas is an HTML element which can be used to draw graphics using scripting.
