Class GraphDigitizerApp

java.lang.Object
javafx.application.Application
com.digitizer.ui.GraphDigitizerApp
public class GraphDigitizerApp extends javafx.application.Application
Main application class for Graph Digitizer.

This is the JavaFX application entry point. It prepares the primary application state (calibration and datasets), constructs the primary MainWindow, and wires accessibility and theming features. Use main(String[]) to start the application from the command line.

Logging: The application uses SLF4J with a Log4j2 backend. The configuration file log4j2.xml defines console, rolling file, and JSON appenders. To enable fully asynchronous logging (lower latency on the JavaFX thread) start the JVM with: 

   -DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
This activates the <AsyncRoot> logger in the configuration. The JSON log (graph-digitizer.json) is newline-delimited for easy ingestion.

Fields documented below are application-wide defaults used to create the initial datasets and to provide versioning information.

Packaging: See `docs/JPACKAGE.md` and `scripts/README.md` for guidance on creating runtime images and native installers via `jlink` and `jpackage` (including multi-architecture MSI generation notes).
