This slider is built with vanilla JS. It's reusable, customizable and easy to use.

1. Define an option object.

const exampleOptions = {
    DOMselector: string,
    sliders: [
      {
        radius: number,
        min: number,
        max: number,
        step: number,
        initialValue: number,
        color: string,
        displayName: string
      }
    ]
};

Additional explanation:

• selector -> your container selector (i.e. #yourSelector, can be any valid selector)
• sliders -> array of options objects for sliders
• radius -> radius of the slider (i.e. 100)
• min -> minimum value of the slider (i.e. 100)
• max -> maximum value of the slider (i.e. 100)
• step -> value step (i.e. 10)
• initialValue -> value of the slider on initialization (i.e. 50)
• color -> color of the slider (valid hex code value)
• displayName -> name of the legend item (any string)

2. Make a new instance of the Slider Class and call the draw() method

const slider = new Slider(exampleOptions);
slider.draw();

That's it!
