Tree layout dynamically

[u s s ramaraju]

Hi Group,

i want to draw tree layout dynamically
but i don't want to use json/csv/tsv
i want to draw it using two arrays containing child and parent
any one have any idea how can i achieve this?

Hi Ramaraju,

Let's see if this helps:

• In order to create a treemap, you need data shaped by d3.hierarchy()
• In order to create a hierarchy, you need data shaped by d3.stratify()
• In order to stratify, you need to combine your two arrays into a single array of objects that looks something like this (from the d3.stratify() docs):
  

[
  {"name": "Eve",   "parent": ""},
  {"name": "Cain",  "parent": "Eve"},
  {"name": "Seth",  "parent": "Eve"},
  {"name": "Enos",  "parent": "Seth"}
]

Are you able to do that?

Cheers,

Seemant
