J'essaye d'obtenir ces diagrammes de beignets avec l'anneau multiple fonctionnant. Ceci utilise d3js v4. Ceci est une continuation d'un autre post où cela fonctionnait dans v3(). Le chemin créé apparaît toujours M0,0Z. Quelqu'un pourrait-il me dire où est-ce que cela se passe mal? Je reçois également Expected lenght NaN dans la console.Diagramme de donut en anneau multiple utilisant D3js v4
