Returns the difference between adjacent tick values if the same arguments were passed to d3.ticks:
a nicely-rounded value that is a power of ten multiplied by 1, 2 or 5.
Note that due to the limited precision of IEEE 754 floating point, the returned value may not be exact decimals;
use d3-format to format numbers for human consumption.
Parameters
start: number
Start value for ticks
stop: number
Stop value for ticks
count: number
count + 1 is the approximate number of ticks to be returned by d3.ticks.
