d3 n'est pas défini - ReferenceError

Je suis en train d'utiliser une "fantaisie graphique", à http://bl.ocks.org/kerryrodden/7090426:

La façon dont je l'ai fait c'était pour télécharger le code et il suffit d'éditer le fichier CSV pour correspondre à mes données. Ensuite, j'ai simplement ouvert le .html-fichier dans Firefox pour voir le graphique interactif. Cependant, son utilisation à un autre ordinateur, j'obtiens les erreurs suivantes:

ReferenceError: d3 n'est pas défini séquences.js:25

ReferenceError: d3 n'est pas défini index.html:28

Que je n'ai presque aucune connaissance de d3 ou javascript, je suis un peu perdu.
Qui de vous me donner un indice de ce qui est à l'origine des erreurs et comment je dois corriger le code?

J'ai fait une simple modification du code de rendre les suivantes:

Javascript:

//Dimensions of sunburst.
var width = 750;
var height = 600;
var radius = Math.min(width, height) / 2;
//Breadcrumb dimensions: width, height, spacing, width of tip/tail.

};
//Mapping of step names to colors.

//row, and can receive the csv as an array of arrays.
