Lorsque l’on pr\u00e9sente des hi\u00e9rarchies \u00e0 plusieurs niveaux o\u00f9 les anneaux internes repr\u00e9sentent des cat\u00e9gories de haut niveau et les anneaux externes d\u00e9composent les sous-cat\u00e9gories, le Diagram en \u00e9toile<\/strong> propose une alternative radiale claire aux cartes en arbre. En disposant les cat\u00e9gories imbriqu\u00e9es en anneaux concentriques, les diagrammes en \u00e9toile permettent aux utilisateurs d’explorer des proportions structurelles multi-niveaux, des relations parent-enfant et des chemins de distribution<\/em> dans un espace compact \u2014 par exemple des cat\u00e9gories de produits mondiaux, des organigrammes ou des parcours d’abandon utilisateur \u00e0 plusieurs \u00e9tapes.<\/p>\n

Le fonctionnement des diagrammes en \u00e9toile<\/h2>\n

Dans Apache ECharts, les diagrammes en \u00e9toile utilisent type : 'sunburst'<\/code>. Similaire aux cartes en arbre, la s\u00e9rie attend une structure arborescente imbriqu\u00e9e dans le donn\u00e9es<\/code> tableau o\u00f9 les objets parents contiennent enfants<\/code> tableaux. Le moteur affiche le n\u0153ud racine ou les cat\u00e9gories de niveau sup\u00e9rieur dans le cercle le plus interne et \u00e9tend les sous-cat\u00e9gories vers l’ext\u00e9rieur \u00e0 travers les couches d’anneaux concentriques.<\/p>\n

1. Configuration de base<\/h3>\n

Pour construire un diagramme en \u00e9toile basique, fournissez un jeu de donn\u00e9es arborescent imbriqu\u00e9 et d\u00e9finissez type : 'sunburst'<\/code> \u00e0 l’int\u00e9rieur de votre objet s\u00e9rie :<\/p>\n
