Se giochi con l'albero pieghevole qui sotto vedrai che quando arrivi alla fine dell'albero e espandi e comprimi i nodi le linee stanno facendo cose strane e non sono del tutto sicuro di ciò che guida il comportamento o se la mia riscrittura di enter link description here è completamente fuori base. Sono uscito da una struttura dati piatta e ho utilizzato stratify per trasformarlo in un layout ad albero. L'unico problema finora è la transizione di linea ... qualche pensiero?d3.js v4 transizione del link wacky nell'esempio di albero comprimibile

'var link = svg.selectAll ("path.link") .data (collegamenti, funzione (d) {return d.id;}); 'è stato abbastanza sufficiente per farlo funzionare. Grazie per avermi indicato nella giusta direzione !! – Tekill
@Yourinium oh yeah - 'd.id' funziona perché c'è sempre un solo collegamento/genitore per bambino. – meetamit
grazie per il tuo aiuto @meetamit – Tekill
