The linear.nice(count) function.
This nice function is a utility in D3 that adjusts the scale's domain to "nice"
round numbers. It modifies the start and stop values of the domain to align them with the step
size calculated for the given number of ticks. This ensures the ticks are well-spaced and easy
to read.
Initial Domain: [6.345, 9.345]
Initial start: 6.345, stop: 9.345
Iteration 1:
Computed step: -5
Adjusting for step < 0:
Before adjustment - start: 6.345, stop: 9.345
After adjustment - start: 6.2, stop: 9.4
Stored prestep: -5
Iteration 2:
Computed step: -2
Adjusting for step < 0:
Before adjustment - start: 6.2, stop: 9.4
After adjustment - start: 6, stop: 9.5
Stored prestep: -2
Iteration 3:
Computed step: -2
Converged. Updating domain...
Final Domain: [6, 9.5]
