jQuery(document).ready(function ($) {

var getSites = function () {

    var ctx = $("#bubble-chart");
    $.ajax({
        url: 'http://127.0.0.1/projets/Multi_Evaluation_Tool/api/data.php',

        dataType: 'JSON',
        success: function (results) {

            var dynamicColors = function () {
                var r = Math.floor(Math.random() * 255);
                var g = Math.floor(Math.random() * 255);
                var b = Math.floor(Math.random() * 255);
                return "rgb(" + r + "," + g + "," + b + ")";
            };

            var sites = [];

            for (var i = 0; i < results.length; i++) {

                var site = {
                    label: results[i].libelle_site.toString(),
