Unified Data Visualization Framework for Dynamic and Static Graphics // Provides a unified API for creating data visualizations across dynamic and static rendering modes. Visualizations are defined once using a specification object and can be rendered with 'highcharter', 'ggplot2', or other supported packages without modifying user code. The package supports declarative and layered workflows, reusable themes and colour palettes, optional 'JavaScript' enhancements, export tools, and interactive exploration through 'shiny' applications.
