SVG stands for Scalable Vector Graphics and it is a language for describing 2D-graphics and graphical applications in XML and the XML is then rendered by an SVG viewer.
SVG is mostly useful for vector type diagrams like Pie charts; Two-dimensional graphs in an X, Y coordinate system etc.
Embedding SVG in HTML5
HTML5 allows embedding SVG directly using <svg>...</svg> tag which has following simple syntax
<!DOCTYPE html>
<head>
<title>SVG</title>
<meta charset="utf-8" />
</head>
<body>
<h2>HTML5 SVG Shape</h2>
<svg xmlns="http://www.w3.org/2000/svg">
...
</svg>
<body>
</html>
Following is the HTML5 version of an SVG example which would draw a different – different shape using <…> tag.
HTML5 - SVG Circle
Following is the HTML5 version of an SVG example which would draw a cricle using <circle> tag:
<svg id="svgelem" xmlns="http://www.w3.org/2000/svg">
<circle id="redcircle" cx="100" cy="100" r="50" fill="LightGray" />
</svg>
Note:
id: This is a user define attribute that used for as a Names an element for use with Cascading Style Sheets.
cx, cy: Used for set padding horizontal and vertical.
r: radius of circle.
fill: fill the color of circle.
HTML5 - SVG Rectangle
Following is the HTML5 version of an SVG example which would draw a rectangle using <rect> tag:
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<rect id="redrect" width="300" height="100" fill="red" />
</svg>
Note:
Width: This is a numeric value, specifies the width of tables, images, or table cells.
Height: This is a numeric value, specifies the height of tables, images, or table cells.
HTML5 - SVG Line
Following is the HTML5 version of an SVG example which would draw a line using <line> tag:
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<line x1="0" y1="0" x2="200" y2="100"
style="stroke:red;stroke-width:2"/>
</svg>
Note:
X1, y1: Start origin point.
X2, y2: End origin point.
Style: This is a CSS Style sheet, specifies an inline style for an element.
HTML5 - SVG Ellipse
Following is the HTML5 version of an SVG example which would draw an ellipse using <ellipse> tag:
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<ellipse cx="100" cy="50" rx="100" ry="50" fill="red" />
</svg>
HTML5 - SVG Polygon
Following is the HTML5 version of an SVG example which would draw a polygon using <polygon> tag:
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<polygon points="20,10 300,20, 170,50" fill="red" />
</svg>
HTML5 - SVG Polyline
Following is the HTML5 version of an SVG example which would draw a polyline using <polyline> tag:
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<polyline points="0,0 0,20 20,20 20,40 40,40 40,60" fill="red" />
</svg>
HTML5 - SVG Gradients
Following is the HTML5 version of an SVG example which would draw a ellipse using <ellipse> tag and would use <radialGradient> tag to define an SVG radial gradient.
Similar way you can use <linearGradient> tag to create SVG linear gradient.
<svg id="svgelem" height="200" xmlns="http://www.w3.org/2000/svg">
<defs>
<radialGradient id="gradient" cx="50%" cy="50%" r="50%"
fx="50%" fy="50%">
<stop offset="0%" style="stop-color:rgb(200,200,200);
stop-opacity:0"/>
<stop offset="100%" style="stop-color:rgb(0,0,255);
stop-opacity:1"/>
</radialGradient>
</defs>
<ellipse cx="100" cy="50" rx="100" ry="50"
style="fill:url(#gradient)" />
</svg>
HTML5 – SVG Paralellogram
Following is the HTML5 version of an SVG example which would draw a paralellogram using <polygon> tag:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1"> <polygon points="200,100 330,100 260,230 130,230" style="fill:LightGray;stroke:black;stroke-width:1" />
</svg>
