PS<$>D3 - Type-Safe D3 Visualizations in PureScript

• Type-safe D3 visualizations in PureScript
• Better fit for functional programming while retaining D3 performance in the browser
• Declarative Tree API - describe what you want, library renders it
• Same tree can render to DOM (D3), Mermaid diagrams, or English descriptions
• Preserves D3's flexibility while adding compile-time safety
• Attributes are type-checked per element (can't put cx on a Rect)

Why use it

• No runtime coercion/casting of data in bindings
• Compiler catches attribute mismatches
• Multiple interpreters from single visualization definition
• Pure PureScript layout algorithms (Sankey, tree, pack) - no D3 layout dependency
• Much better suited to re-use, library creation, complex apps, data viz as control surface
• Higher-level abstractions for graphs and networks using simulation with updates

Packages

• psd3-selection - Core selection system, Tree API, type-safe attributes
• psd3-simulation - Force-directed graphs, simulation engine
• psd3-layout - Layout algorithms (tree, treemap, pack, Sankey, cluster)

Two API levels

• Tree API - declarative, for static charts (bar, line, tree, Sankey)
• PSD3 API - lower-level, for simulations and interactive viz
