How To Create Svg In Javascript

Print SVG HTML with Javascript Stack Overflow

As a web developer, you should always be looking for ways to enhance the user experience on your website. One way to do this is through the use of Scalable Vector Graphics (SVGs). SVGs are an XML-based vector image format that can be easily scaled to any size and are supported by most modern web browsers. In this article, we will explore how to create and manipulate SVGs in JavaScript.

What is an SVG?

SVGs are a type of image format that uses vector graphics to create images. Vector graphics are images that are composed of points, lines, and shapes, rather than pixels. This means that they can be scaled to any size without losing the quality of the image. SVGs can be used to create everything from simple icons to complex animations and can be easily manipulated using JavaScript.

Creating an SVG

Creating an SVG in JavaScript is relatively simple. The first step is to create an HTML element, which is the root element of an SVG image. This element will contain all of the shapes, paths, and other elements that make up the image. The element should also include the appropriate width and height attributes, which determine the size of the image.

Once the element has been created, you can begin to add shapes, paths, and other elements to it. All of these elements can be created using the appropriate HTML tags, such as for a rectangle or for a circle. These elements should also include the appropriate attributes, such as width and height for a rectangle, or cx and cy for a circle.

Manipulating SVGs

Once an SVG has been created, it can be manipulated using JavaScript. This can be done by selecting the SVG element or one of its child elements and then manipulating its attributes. For example, to change the size of a rectangle, you could select the element and then set its width and height attributes to the desired values.

You can also use JavaScript to animate an SVG. This can be done by setting the appropriate attributes of an SVG element to a specific value over a period of time. For example, you could set the x-coordinate of a circle to a specific value, and then use JavaScript to gradually increase the x-coordinate over time. This would result in the circle gradually moving across the screen.


In this article, we have explored how to create and manipulate SVGs in JavaScript. We have seen that creating an SVG is relatively simple and can be done by creating an element and then adding shapes, paths, and other elements to it. We have also seen that SVGs can be manipulated using JavaScript, which can be used to animate the SVG or to change its attributes. With these tools, you can create powerful and engaging user experiences on your website.
