Apart from alt text, our data won’t be read aloud by screen readers and the data points in the charts themselves won’t be able to be interacted with by mouse, touch, or keyboard input. However, we’ll lose most of the benefits of inline SVG, such as accessibility and interactivity. This is great because it will look good and scale well. Making a chart with SVG can be as easy as designing one in Illustrator, or your vector-based design app of choice, export it as SVG, and popping it straight into the markup using an tag: What’s the simplest approach to making a chart with SVG? Charts with There are plenty of SVG-based chart frameworks out there to help.SVGs are accessible to screen readers (with a little bit of work).

We can update this with two more key points that are useful for charts: Design control like interactivity and filters.Scales to any size without losing clarity (except very tiny sizes).In our compendium of SVG we described the format’s general advantages like this: It has advantages that apply to making charts, too. The SVG image format isn’t just for icons or simple images. This practice makes a lot of sense, even if the element alone is not best suited to the task of graph-making. For instance, Filament Group made a jQuery plugin called Visualize, which grabs the data from a table element and then creates a canvas chart. Yet there are alternatives to this standalone canvas approach. With SVG, you get semantics and accessibility as well as interactivity with JavaScript out of the box. So an HTML5 Canvas would require double the amount of maintenance. You need to also take extra measures to map the content and interactivity between the contents of the canvas and the fallback, so that screen readers know which element is being interacted with. You would need to create a secondary content between the opening and closing tags to serve as fallback and as accessible content. HTML5 Canvas can also be used to create such visualisations, but the content of the canvas are not part of the DOM and are thus not accessible by screen readers. However, Sara Soueidan suggests avoiding this method, too: There are plenty of other ways in which you could make a chart for the web, most notably by using the canvas element. Generally speaking, it’s best to make charts with a combination of SVG, JavaScript, and CSS. I argued that this wasn’t the best option in most cases there are just too many tricky design and development hurdles to overcome. In my first post about making charts, I looked at methods that solely relied on CSS.
