## What it is
Dex is a desktop data exploration and visualization application written in Java/Groovy on top of JavaFX. It combines ETL capabilities, machine learning integration (SMILE and R), and 50+ visualization types that can be published to the web.

## Use cases
- visualize csv data with interactive charts
- explore and transform datasets before analysis
- create web-based data visualizations from databases
- apply machine learning to tabular data
- build network and chord diagrams from relational data
- etl data between files and databases

## When to choose
- you want a GUI-based data exploration tool on the JVM
- you need ETL plus visualization in a single desktop app
- you want to publish D3-style visualizations to the web from Java

## When to avoid
- you need a Python or R-native workflow
- you require actively maintained software with recent releases
- you need a lightweight scriptable library rather than a full desktop application

## Facets
- artifact type: application
- maturity: maintenance
- function: data-visualization, etl, machine-learning, nlp
- domain: data-visualization, data-science
- platform: cross-platform, jvm
