What is different between d3.scale.linear() and d3.scaleLinear().

To create scales showing the linear relationship between the output and input we use d3.scale.linear() and d3.scaleLinear(). The domain and range of the scale are set by default at the interval (0,1) which expresses the function y = x. It can be used for flipped range, nice bounds, round ranges, non-numerical range, camping, etc.

There is a minor difference between d3.scale.linear() and d3.scaleLinear() which is on the basis of its use.

• If you want to create d3.js linear scale on version 3 then use API d3.scale.linear()
• If you want to create d3.js linear scale on version 4 and 5 then use API d3.scaleLinear()
