🤔 What is SVG? 🤔

😎 Scalable Vector Graphic 😎

Simplified SVG markup.

<svg viewBox="0 0 100 100">
    <path d="M10 10H90V90H10Z"/>
    <circle cx="50" cy="50" r="40"/>
</svg>

SVG is an alternate universe version of HTML, focused on graphics instead of documents.

- Richard Westenra

🙌 SVG has a DOM 🙌

🙌 Illustrations... 🙌

that you can manipulate with code!

But...

we can style HTML elements to make animations too.

SVG is built for drawing

in a way that HTML

and CSS are not.

Making a chart with SVG can be as easy as designing one, exporting it and popping it straight into the markup.
