Creating Svg Lines With Javascript

Scalable Vector Graphics, or SVGs, are a popular way to create interactive graphics on the web. They’re great for animation, as well as for displaying complex shapes and text. SVG lines can be used to draw lines, shapes and patterns, and are often used to create a variety of different graphical effects. In this article, we’ll look at how to create SVG lines with JavaScript.

What is SVG?

SVG stands for Scalable Vector Graphics and is an XML-based markup language for describing two-dimensional vector graphics. SVG graphics can be created using any text editor, though most designers prefer to use dedicated software such as Adobe Illustrator or Inkscape. SVG graphics are resolution-independent, meaning they can be scaled up or down without losing quality. They can also be manipulated using JavaScript, which makes them an ideal choice for creating interactive graphics.

How to Create an SVG Line in JavaScript

Creating an SVG line in JavaScript is straightforward. First, we need to create a svg element. This element will act as our canvas and will contain all of our drawn lines. We can then create a line element and add it to the svg element. We can then set the starting and ending points of the line by using the x1, y1, x2 and y2 attributes. Finally, we can set the line’s color and width using the stroke and stroke-width attributes.

Example Code

Here’s an example of how to create an SVG line in JavaScript:

 var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
 var line = document.createElementNS("http://www.w3.org/2000/svg", "line");
 line.setAttribute("x1", "0");
 line.setAttribute("y1", "0");
 line.setAttribute("x2", "100");
 line.setAttribute("y2", "100");
 line.style.stroke ="#ff0000";
 line.style.strokeWidth ="2px";
 svg.appendChild(line);
 document.body.appendChild(svg);

This code will create an SVG line with a starting point of (0,0) and an ending point of (100,100). The line will be red and 2 pixels wide.
