JQuery progress bar plugin is not working

Question

$(window).scroll(function(){
  $('svg.radial-progress').each(function( index, value ) { 
    // If svg.radial-progress is approximately 25% vertically into the window when scrolling from the top or the bottom
    if ( 
        $(window).scrollTop() > $(this).offset().top - ($(window).height() * 0.75) &&
        $(window).scrollTop() < $(this).offset().top + $(this).height() - ($(window).height() * 0.25)
    ) {
        // Get percentage of progress
        percent = $(value).data('percentage');
        // Get radius of the svg's circle.complete
        radius = $(this).find($('circle.complete')).attr('r');
        // Get circumference (2πr)
        circumference = 2 * Math.PI * radius;
        // Get stroke-dashoffset value based on the percentage of the circumference
        strokeDashOffset = circumference - ((percent * circumference) / 100);
        // Transition progress for 1.25 seconds
        $(this).find($('circle.complete')).animate({'stroke-dashoffset': strokeDashOffset}, 1250);
    }
  });
}).trigger('scroll');

This plugin is working in demo but not in my project.Is there any problem in the js or this plugin is just obsolete .I have added the link so anyone can check the whole html,css of the plugin.Any kind of help would be appreciated. https://www.jqueryscript.net/loading/Radial-Progress-Bar-jQuery-SVG-CSS3.html
