## What it is
Explorer is an Elixir library providing series (one-dimensional) and dataframes (two-dimensional) for fast data exploration and manipulation. It is backed by NIF bindings to the Polars library and offers a dplyr-inspired, immutable API with support for CSV, Parquet, NDJSON, and Arrow IPC formats.

## Use cases
- work with dataframes in Elixir
- explore and manipulate tabular data in Elixir
- read and write CSV and Parquet files in Elixir
- filter and transform datasets with a dplyr-like API
- analyze large datasets fast in Elixir
- load data from S3 or databases into dataframes

## When to choose
- you're doing data science or data manipulation in Elixir or Livebook
- you want Polars-level performance with an idiomatic Elixir API
- you need immutable, tidy-data-style dataframe operations

## When to avoid
- you need a dataframe library outside the Elixir ecosystem
- you prefer SQL-based analytics via DuckDB (consider Dux instead)
- you need remote/Spark dataframe backends that are not yet implemented

## Facets
- artifact type: library
- maturity: active
- function: data-science, etl, csv, json
- domain: data-science, analytics
- platform: elixir, rust, cross-platform
- tags: dataframes, polars, series, dplyr-inspired, parquet, arrow, data-engineering
