It appears to be utilizing this as a dependency. To adjust the circle size, you must include the size property, which defaults to 100:
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percent / 100,
thickness: 14,
fill: {
color: '#1B58B8'
},
size: 300 // <-- here, changing the size modifies the circle's radius
})
To prevent overlapping circles, you also need to tweak the CSS by increasing the width of the .progressbar element:
.progressbar {
display: inline-block;
width: 300px;
margin: 25px;
}
The complete example would resemble this:
/**
* index.js
* - All our useful JS goes here, awesome!

*/
console.log("JavaScript is amazing!");
$(document).ready(function($) {
function animateElements() {
$('.progressbar').each(function() {
var elementPos = $(this).offset().top;
var topOfWindow = $(window).scrollTop();
var percent = $(this).find('.circle').attr('data-percent');
var percentage = parseInt(percent, 10) / parseInt(100, 10);
var animate = $(this).data('animate');
if (elementPos < topOfWindow + $(window).height() - 30 && !animate) {
$(this).data('animate', true);
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percent / 100,
thickness: 14,
fill: {
color: '#1B58B8'
},
size: 300
}).on('circle-animation-progress', function(event, progress, stepValue) {
$(this).find('div').text((stepValue * 100).toFixed(1) + "%");
}).stop();
}
});
}
// Show animated elements
animateElements();
$(window).scroll(animateElements);
});
