SVG Circle

The tag <circle> is used to draw the circle with a center point and radius.

It includes cx, cy and r as main attributes that are described as:

The cx and cy attributes defines the x and y coordinates of the center of the circle. The default center value is (0, 0).
The r attribute defines the radius of the circle.

Let's see a few examples to understand SVG Circle.

Example 1: Simple circle

<html>
<body>
<svg height="500" width="500">
<circle cx="80" cy="80" r="40" fill="#0f0fff";/>
<circle cx="200" cy="80" r="60" fill="#0fffff";/>
<circle cx="350" cy="80" r="80" fill="#ffff00";/>
</svg>
</body>
</html>

Output

Simple circle

Example 2: Circle with multiple strokes.

<html>
<body>
<svg height="500" width="500">
<circle cx="80" cy="80" r="60" fill="tomato" stroke="#0f0fff" stroke-width="3"/>
<circle cx="210" cy="80" r="60" fill="tomato" stroke="#0f0fff" stroke-width="5"/>
<circle cx="340" cy="80" r="60" fill="tomato" stroke="#0f0fff" stroke-width="8"/>
</svg>
</body>
</html>

Output

Circle with different strokes

Example 3: Circle with multiple dashed strokes.

<html>
<body>
<svg height="500" width="500">
<circle cx="80" cy="80" r="60" fill="#0fff0f" stroke="#0f000f" stroke-width="3" stroke-dasharray="10 3";/>
<circle cx="210" cy="80" r="60" fill="#0fff0f" stroke="#0f000f" stroke-width="5" stroke-dasharray="10 5";/>
<circle cx="340" cy="80" r="60" fill="#0fff0f" stroke="#0f000f" stroke-width="8" stroke-dasharray="10 7";/>
</svg>
</body>
</html>

Output

Example 4: Circle with multiple strokes only.

<html>
<body>
<svg height="500" width="500">
<circle cx="80" cy="90" r="40" fill="none" stroke="#0f0f0f" stroke-width="3";/>
<circle cx="190" cy="90" r="60" fill="none" stroke="#00ff00" stroke-width="5";/>
<circle cx="340" cy="90" r="80" fill="none" stroke="tomato" stroke-width="8";/>
</svg>
</body>
</html>

Output

Circle with different strokes only

The following produces a circle with multiple dashed strokes only.

<html>
<body>
<svg height="500" width="500">
<circle cx="80" cy="90" r="40" fill="none" stroke="#00cc00" stroke-width="3" stroke-dasharray="10 2";/>
<circle cx="190" cy="90" r="60" fill="none" stroke="#cc0000" stroke-width="5" stroke-dasharray="10 5";/>
<circle cx="340" cy="90" r="80" fill="none" stroke="#0c0c0c" stroke-width="8" stroke-dasharray="10 8";/>
</svg>
</body>
</html>

Output

Circle with different dashed strokes only

The following produces a circle overlapped with multiple strokes/dashed strokes only.

<html>
<body>
<svg height="500" width="500">
<circle cx="100" cy="100" r="30" fill="none" stroke="#c0ff00" stroke-width="3";/>
<circle cx="100" cy="100" r="60" fill="none" stroke="#0000cc" stroke-width="5";/>
<circle cx="100" cy="100" r="90" fill="none" stroke="#066600" stroke-width="8";/>
<circle cx="300" cy="100" r="30" fill="none" stroke="#00cc00" stroke-width="3" stroke-dasharray="10 2";/>
<circle cx="300" cy="100" r="60" fill="none" stroke="#cc0000" stroke-width="5" stroke-dasharray="10 5";/>
<circle cx="300" cy="100" r="90" fill="none" stroke="#660066" stroke-width="8" stroke-dasharray="10 8";/>
</svg>
</body>
</html>

Output
