d3.js - c3js / highcharts multi series nested json chart with many data points -

i'm trying figure out whether possible generate c3js chart following json structure.

[   {     "name": "linetest1",     "data": [       {"date": 1452049754,"value": 118},       {"date": 1452049759,"value": 120}     ]   },   {     "name": "linetest2",     "data": [       {"date": 1452049758,"value": 54},       {"date": 1452049759,"value": 59}     ]   } ] 

i've seen mentions in documentations of using xs or keys: chart options appear setting x , y axis specific key in flat data array although haven't been able find docs or examples / google related multi series nested json, or how handle that.

with data above objective render 2 lines on chart. line 1 having title of linetest1 , line2 having title of linetest2. data points x axis line 1 use data.date timeseries , data.y value.

is possible? if not there better way this? if possible explain how can accomplished? loading data via url, have seen mentions stating better use d3 load json instead of using c3 like:

url: '/rest/chart_data_endpoint.json', type: 'line', mimetype: 'json' 

i have not yet been able single chart working current json structures don't have fiddle start with. other dilemma there may several lines , each have 5k data points / line? i'm curious whether highcharts not better option seem claim can 1mil points ajax load although i'm still in same boat not knowing js or libraries enough know pick or start.
