🙋 Introduction

In the realm of Scalable Vector Graphics (SVG), the polyline is a versatile element that allows for the creation of complex shapes and paths. Unlike basic shapes such as rectangles and circles, a polyline consists of a series of connected straight lines, enabling the formation of intricate designs and outlines.

This guide will walk you through the syntax, attributes, and practical applications of SVG polylines, empowering you to harness their potential in your web development projects.

💡 Syntax

To define a polyline in SVG, you utilize the <polyline> element. This element encapsulates a sequence of points, each denoting the vertices of the polyline. The basic structure is as follows:

Syntax

Copied

<svg>
  <polyline points="x1,y1 x2,y2 x3,y3 ..." />
</svg>

Here, points attribute represents a list of coordinates, with each pair separated by spaces and each coordinate pair separated by commas. These coordinates determine the position of the vertices that form the polyline.

🧰 Attributes

points: Specifies the coordinates of the vertices of the polyline. These coordinates are defined as pairs of x and y values, indicating the position of each vertex.
Additional attributes such as fill, stroke, and stroke-width can be applied to style the polyline.

📄 Example

Let's create a simple SVG polyline:

index.html

Copied

<svg width="200" height="200">
  <polyline points="50,50 100,25 150,50 125,100 75,100" fill="none" stroke="black" stroke-width="2" />
</svg>

🧠 How it works?

In this example, we've defined a five-point polyline, forming a polygonal shape. The vertices are positioned at (50,50), (100,25), (150,50), (125,100), and (75,100), creating a closed shape. The polyline is styled with a black stroke and a stroke width of 2 units.

🎉 Conclusion

SVG polylines offer a powerful tool for creating intricate shapes and paths within your web projects. By understanding their syntax and attributes, you can leverage polylines to construct detailed graphics, diagrams, and illustrations with precision and elegance.

Experiment with different coordinate values and styling options to unleash the full potential of SVG polylines in your designs.
