Fahmatrix: A Lightweight Pandas Alternative for Java

Fahmatrix is a lightweight, modern Java library for working with tabular data, inspired by Python's Pandas and designed to simplify data understanding on the JVM. It offers an intuitive API for CSV reading and previewing, row filtering and column selection, and upcoming features like aggregations, grouping, and sorting. Fahmatrix currently has no external dependencies and can be downloaded as a JAR file from GitHub or used via Maven/Gradle (to be added in future versions). Key features include loading CSV files into DataFrames, pretty-printing data, `head()`/`tail()` functions, various aggregation functions, row filtering and column selection, groupBy and pivot tables, data export, and type inference and conversion. Fahmatrix empowers Java developers to work with tabular data efficiently without leaving the JVM.
