javascript - d3.js area chart - json data not binding to chart -

i'm stumped trying json data render. thank suggestions below made progress trying solutions not quite there yet.

thank you.

jsfiddle: http://jsfiddle.net/tommy6s/9dv55t4q/  d3.json("http://www.corsproxy.com/dvl.thomascooper.com/data/kruggerrand.json", function(error, data) { ...fiddle data...} 

the variable type undefined. it's not necessary.
