Scales

Linear and band scale mapping for data visualization. Scales transform values between data domains and visual ranges.

Linear scales

• scaleLinearMap — Map a domain value to its corresponding range value.
• scaleLinearInvert — Invert a linear scale, mapping from range back to domain.
• scaleLinearTicks — Generate nicely-spaced tick values for a domain.

Band scales

• scaleBandMap — Map a categorical value through a band scale, returning position and sizing info.
