Bonjour à tous, j'ai trouvé un code sur internet pour faire une jauge sous javascript qui me plaît plutôt pas mal, le voici:

<!DOCTYPE html>

    <style>
        .liquidFillGaugeText { font-family: Helvetica; font-weight: bold; }
    </style>
</head>
<body>
    <svg id="fillgauge1" width="50%" height="250"></svg>
    <button id="essai">Essai</button>

<script language="JavaScript">
    $('#essai').click(function(){ 
        var gauge1 = loadLiquidFillGauge("fillgauge1", 55);
        var config1 = liquidFillGaugeDefaultSettings();
        config1.circleColor = "#FF7777";
        config1.textColor = "#FF4444";
        config1.waveTextColor = "#FFAAAA";
        config1.waveColor = "#FFDDDD";
        config1.circleThickness = 0.2;
        config1.textVertPosition = 0.2;
        config1.waveAnimateTime = 1000;
    });
</script>
</body>

Ce qui donne ce résultat:

J'aimerais crée cette jauge dynamiquement, c'est-à-dire l'ajouter dans le DOM, en cliquant sur un bouton, j'ai donc écrit:

<!DOCTYPE HTML>
<head>
<meta charset='utf-8'/>
</head>
  <body>
    <button id="essai">Apparaître</button>
    <button id="creer">Créer</button>
    <script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
    <script src="https://d3js.org/d3.v3.min.js"></script>
    <script src="/socket.io/socket.io.js"></script>

    <script>
      $('#essai').click(function(){
      var volinit = "55";
      var gauge = loadLiquidFillGauge("gauge", volinit);
      var config = liquidFillGaugeDefaultSettings();
      config.circleColor = "#FF7777";
      config.textColor = "#FF4444";
      config.waveTextColor = "#FFAAAA";
      config.waveColor = "#FFDDDD";
      config.circleThickness = 0.2;
      config.textVertPosition = 0.2;
      config.waveAnimateTime = 1000;
      });

      $('#creer').click(function(){
      var svg = document.createElement("svg");
      svg.setAttribute("id", "gauge");
      svg.setAttribute("width", "565");
      svg.setAttribute("height", "50");
      document.getElementsByTagName("body")[0].appendChild(svg);
      });

Ainsi que tout le code contenant les fonctions pour crée la jauge (le même que celui écrit plus haut).
Mais en faisant cela, ma jauge ne s'affiche pas:

Et je n'ai aucun message d'erreur.
Voilà, si quelqu'un a une explication ou une solution je suis preneur, merci d'avance!

Bonjour,

N'aurais tu pas enlevé

<script src="jauge_ronde.js" language="JavaScript"></script>

Ainsi que le "style" ?

Qu'as tu d'affiché dans la CONSOLE de ton navigateur lorsque tu cliques sur ton bouton ?
