Description
It’d be nice if there were a transform: "si" or units: "si" scale option that automatically computed the appropriate SI units based on the associated channel values, and used this to apply a scale transform and append the appropriate units to the scale label. Ref. https://github.com/observablehq/plot/issues/1612#issuecomment-1685075869, where the appropriate units are 1e6 (micros) and the scale label should have “ (µ)” appended.

Research direction
Start by reading the existing scale-option and associated channel-value handling, then review the referenced discussion for the expected micros example. The work is done when an SI option infers the appropriate unit transform and appends the matching SI symbol to the scale label, with coverage for the documented case.
