 **Optimal Binning Histograms for Python**
 
 Khisto is a Python library for creating histograms using the **Khiops optimal binning algorithm**. Unlike standard histograms that use fixed-width bins or simple heuristics, Khisto automatically determines the optimal number of bins and their variable widths to best represent the underlying data distribution.

 - **Variable-Width Bins**: Captures dense regions with fine bins and sparse regions with wider bins.
 - **NumPy Compatible**: Drop-in replacement for `numpy.histogram`.
 - **Matplotlib Integration**: `khisto.matplotlib.hist` works like `plt.hist`.
+- **Core Histogram API**: Inspect every available granularity with `khisto.core.compute_histograms` and `HistogramResult`.
 - **Minimal Dependencies**: Only requires NumPy (matplotlib optional for plotting).
