Special characters in plotly.js causing minification and packaging issues

I have identified an issue in the plotly.js library where special characters, such as σ and μ, are used in a function. This leads to problems during the minification/packaging process, causing certain package managers to fail as they do not correctly interpret these characters.

I found a related issue in the Parcel bundler repository, which has been addressed and fixed. The details can be found here: Parcel Issue #9370

I propose modifying the original plotly.js function to replace the special characters with safer alternatives. Below is the suggested modification:

normal: function(mu, sigma) {
  var n = arguments.length;
  if (n < 2) sigma = 1;
  if (n < 1) mu = 0;
  return function() {
    var x, y, r;
    do {
      x = Math.random() * 2 - 1;
      y = Math.random() * 2 - 1;
      r = x * x + y * y;
    } while (!r || r > 1);
    return mu + sigma * x * Math.sqrt(-2 * Math.log(r) / r);
  };
},

I will try to push a PR myself

Recherchez dans le code source de plotly.js la fonction normal utilisant les paramètres mu et sigma, puis examinez l’issue Parcel associée pour comprendre le contexte du packaging. Remplacez les identifiants problématiques contenant des caractères spéciaux par les noms plus sûrs proposés et vérifiez que la minification et le packaging n’échouent plus.
