Function histogram 

pub fn histogram(data: &[f64], rule: BinRule) -> Result<Histogram, StatsError>

Build a Histogram from data using the chosen BinRule. Non-finite values are ignored.

Errors

• StatsError::EmptyInput if no finite values remain.
• StatsError::ZeroVariance if all values are identical (no range to bin).
• StatsError::InvalidBandwidth if an explicit BinRule::Width or BinRule::Count is non-positive.
