This article mainly introduces the introductory tutorial for using HTML5 to draw SVG vector graphics, including the introduction of basic graphics drawing and simple gradient effects. Note that the old version of IE does not support it well. Friends who need it can refer to it. Below
VG stands for Scalable Vector Graphics, which is a language used to describe 2D graphics. Graphics applications are written using XML, and then the XML is rendered by an SVG reader program.
SVG is mainly used for vector type charts, such as pie charts, two-dimensional charts in X, Y coordinate systems, etc.
SVG became a W3C recommendation on January 14, 2003. You can view the latest version of the SVG specification on the SVG Specification page.

Most web browsers can display SVG, just like they can display PNG, GIF, and JPG graphics. IE users may need to install Adobe SVG Reader to be able to view SVG in the browser.
Embed SVG in HTML5
HTML5 allows us to embed SVG directly using the __ tag. The following is a simple syntax:
<svg xmlns="http://www.w3.org/2000/svg"> ... </svg>
HTML5 - SVG Circle
Here is an HTML5 version of an SVG example, using the
<!DOCTYPE html>
<head>
<title>SVG</title>
<meta charset="utf-8" />
</head>
<body>
<h2 id="HTML-nbsp-SVG-nbsp-Circle">HTML5 SVG Circle</h2>
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<circle id="redcircle" cx="50" cy="50" r="50" fill="red" />
</svg>
</body>
</html>Will work in the latest version of FireFox with HTML5 enabled Produces the following result:
##HTML5 - SVG Rectangle
Here is an HTML5 version of an SVG example, using the
