How to Create a Clickable Circular Menu with SVG Paths?

Creating a Circle with Links on its Border

Introduction

Creating a clickable circle with distinct segments can enhance user interaction and visual appeal. In this article, we will explore how to achieve this using SVG path elements, applying trigonometric equations to calculate coordinates and draw arcs.

Finding Points on a Circle

To create even segments around a circle, we need to calculate the coordinates of specific points along its circumference. This can be done using trigonometric equations:

X Coordinate = (Radius * Cos(Angle in Radians)) X Coordinate of Center

Y Coordinate = (Radius * Sin(Angle in Radians)) Y Coordinate of Center

Angle in Radians = (Angle in Degrees * Math.PI / 180)

Constructing the SVG Path

Once the points are calculated, we can define an SVG path to connect them. The path should start and end at the center point, drawing a line to the starting point and an arc to the endpoint.

For instance, to create a path for a circle with 6 segments, we would use:

<path d="M55,55 L105,55 A50,50 0 0,1 80,98.30z"></path>

Here, 55,55 represents the center point, and the arc shape is defined using the radius (50), sweep degree (0), and angle of rotation (1).
