Designing with SVG: How Scalable Vector Graphics Can Increase Visitor Engagement

Scalable Vector Graphics, more affectionately known as SVGs, are an XML-based graphic format used to display images on the web. Unlike PNGs, JPEGs, and GIFs, which are pixel-based formats, SVGs have their own coordinate system — using a combination of points and math to recreate vector images in browsers.

SVGs are resolution independent, animatable, and scriptable. It's essentially— but.

So if this file format is so versatile, why aren’t more web designers and developers incorporating SVGs into client projects?

Because it’s not a part of their “muscle memory,” the tips and tricks they instantly refer to when approaching design strategy.

Recently, we sat down withChris Coyier— co-founder ofCodePen, author ofA Book Apart’s Practical SVG, and creator ofCSS-Tricks— for aShopify Partner Session webinar, where we chatted about how web designers and developers can incorporate SVG elements into their design toolkits.

During his talk, Chris shared 10 ways you can (and should) use SVG. We’ve compiled five of these tactics into an article to help you easily implement SVG objects into your next client project.

1. Create interactive charts and graphs to show data

Does your client have a lot of customer/service-related data, like how many hours a customer saved by switching to their product? Or maybe how many services they’ve provided, per month, over the last year? Show your client the value of displaying this data on their website, by creating charts and graphs using SVGs. They’re a quick way to impress both your client and their audience. SVGs are easily animated, interactive, and can be used to plot any kind of data.

Because SVG files are composed of math, web designers and developers should use this file format to graphically display analytical and numerical information – like tweets over time, or sales per month. You can use SVGs to create straight lines, curved lines, and differentiate these items with different thicknesses, dashes, gaps, and colors. Smashing Magazine hasa great article about using the Chartist.js— an open-source charting library — to create responsive charts.

Or you can refer to Chris Gannon’s Pen,outlining how to make an interactive SVG chart:

Did we mention that SVG-based charts and graphs can be especially handy for tracking real-time data?

Apart from Chartist.js, there are multiple JavaScript libraries available to help with your charting needs. SitePoint has compiled a list of16 (mostly) free charting librariesthat you might find helpful. Whichever one you choose depends on which features are most important to you – so try out a few to find the right one for your business/client.

2. Morph shapes to add engagement

Shape morphing adds pizzaz to websites or web pages needing a strong graphic element, and they’re a lot easier to implement than you might think.

While you can animate SVG images using CSS, there are limitations, like not being able to animate any of the points that define the actual shape/object. And though you can circumvent these issues using Synchronized Multimedia Integration Language (SMIL), there is a much better (and more powerful) tool available to web designers and developers:GreenSock’sMorphSVG Plugin.

See the PenMorphSVGPlugin from GreenSockby GreenSock (@GreenSock) onCodePen.

Put simply, users can create multiple paths within MorphSVG and, with a single line of code, morph the object in path one into the object in path two. MorphSVG also uses a property that allows users to define how the points in the starting shape are mapped – giving web designers and developers more control over how their object is morphed

Next time you’re working on a client project, try doing some fun morphing animations with their logo (should brand guidelines permit). Or, insert elements that your client’s audience can interact with (like this Tweenmax/MorphSVG mash-up by Craig Point):

3. Draw and manipulate lines to give context

Line drawing using paths is one of the most powerful ways to use SVGs in client projects, as it is a functional, scalable method to illustrate diagrams, workflows, product design, or any other visual representation in a way that is digestible for site users. Essentially,line drawing animation tells storiesabout your client’s business, product, or services and give context to the rest of the page’s content, all by illustrating the intricate design of a product, or recreating a key moment in your client’s history.

An example of this is how Polygon uses SVG line drawing to replicate the PS4 for their initial review of the system:

A more basic example demonstrating the capabilities of SVG line drawing is how Cory Norris uses SVG line drawing to create a bear:

4. Animate interfaces to connect processes

Pasquale D’Silva, animator and software inventor, believes thatusers of a website understand things better when transitions are used. The reasoning being that transitional animations allow our brains to easily connect processes or identify new pieces of information. One of the best examples of a transitional interface is a load screen icon –it keeps moving to let users know that the website hasn’t stopped processing their request.

5. Use SVG icon systems for simplicity

Did you know that there is a specific element in SVGs, specifically made for icons? Even better, this icon functionality is natively built into all internet browsers. Implementing an SVG icon system into your client’s website, or even your own, is a quick win for performance. Noah Blon's pen has somebeautiful examples of weather iconscreated with SVG:

There are many reasons you should use vector icons in lieu of icon fonts and pixel-based images. They’re crisp, have strong CSS control, and can easily match the size of the font around them. Compared to icon fonts, SVG icons are significantly less frustrating to position, they’re easily accessible, and are less likely to fail.

Since SVG files aren’t supported in all (older) browsers, you can useGrunticon, which will automatically fallback to a PNG copy of your icon at any time.
