Düz bir dosyayı okumaya ve bu düz belgeyle bir hiyerarşi oluşturmaya, yakınlaştırılabilir daireler oluşturmak için çalışıyorum. Sorunum, dairemdeki konumunu okuyamıyorum (değişkenin x ve y değeri). Bu kodu buldum: http://bl.ocks.org/mbostock/4063269 ve değişken düğümün özn işlevi (d) id çağrı ... Burada burada saklanan veriler d3
kodum olduğunda pozisyon x ve y "d" doğrudan geçerli:<!DOCTYPE html>
