• Interactive Elements: Built-in support for panning, zooming, brushing, and dragging
• Advanced Layouts: Includes treemaps, force-directed graphs, Voronoi diagrams, and more
• Geographic Mapping: Extensive support for spherical projections with flexible customization
• Data Processing: Robust utilities for CSV parsing, date handling, and statistical operations

Use Cases

• Creating custom, interactive data visualizations
• Building complex statistical and scientific visualizations
• Developing geographic mapping applications
• Implementing dynamic, data-driven graphics
