+  const numberOfTicks =

[nitpick] The fallback value of 2 ticks seems arbitrary. Consider documenting why 2 is chosen as the default, or verify this produces reasonable tick spacing for edge cases where no modulo match is found.

Suggested change

const numberOfTicks =

possibleTickNumbers.find((number) => topValue % (number - 1) === 0) || 2; // Default to 2 ticks if no match

// If no modulo match is found, default to 4 ticks for better chart readability.

// This ensures at least start, end, and two intermediate ticks are present.

const numberOfTicks =

possibleTickNumbers.find((number) => topValue % (number - 1) === 0) || 4;
