//! Cyclomatic complexity histogram construction.

use tokmd_analysis_types::{ComplexityHistogram, FileComplexity};

/// Generate a histogram of cyclomatic complexity distribution.
///
/// Buckets files by cyclomatic complexity: 0-4, 5-9, 10-14, 15-19, 20-24, 25-29, 30+.
///
/// # Arguments
/// * `files` - Slice of file complexity data
/// * `bucket_size` - Size of each bucket (default 5)
///
/// # Returns
/// A `ComplexityHistogram` with counts for each bucket
///
/// # Note
/// This function is planned for integration in v1.6.0.
