Uncaught TypeError: Cannot read property 'linear' of undefined

I'm new to D3 and getting the following error in my demo script -

FirstD3.jsp:31 Uncaught TypeError: Cannot read property 'linear' of undefined

My demo code is as follow

what is causing this error? and how to solve it

In D3 v4 it is no longer named d3.scale.linear(). Use d3.scaleLinear() instead.
