Thanks joshbirk for the method os tagging the svg to a

Hi,
I am new to D3 and want to learn it. I started by implementing your code but getting the below error. Also, I created a custom object named SpeedTest__c.
Error in $A.getCallback() [plumb is not defined]
Callback failed: apex://SpeedTestController/ACTION$getData
Could you please help me to resolve it?
Thanks in advance !
Piyush
