• Statistical Analysis: Means, medians, standard deviations, skewness, kurtosis, and more.
• Data Insights: Missing values, duplicates, outliers, and feature importance.
• Visualizations: ASCII bar plots for data distributions.
• Exportable Results: Save insights as JSON with the e key.
• Lightweight and Fast: Built in Rust for performance.
