//! Helios Core - High-performance visualization engine
//!
//! This crate provides the core visualization engine for Helios, including:
//! - **Canvas2D Rendering**: Universal browser support with TDD implementation
//! - **WebGPU Acceleration**: High-performance GPU rendering (816+ MB/s throughput)
//! - **WebAssembly Integration**: Rust-powered data processing and function export
//! - **Data Processing Pipeline**: Polars integration with efficient data handling
//! - **Chart Specification System**: Compile-time validation and type safety
//! - **Performance Optimization**: Sub-millisecond rendering and adaptive quality
//! - **Test-Driven Development**: Complete TDD methodology with 100% test coverage
//!
//! ## Demo Suite
//!
//! Experience Helios in action with our comprehensive demo suite:
//!
//! ```bash
//! python3 demo-server.py
//! # Open http://localhost:8080 in your browser
//! ```
//!
//! ### Available Demos
//! - **Canvas2D TDD Demo** (`/`) - Test-Driven Development methodology
//! - **WebGPU Demo** (`/webgpu`) - GPU acceleration testing
//! - **WebGPU Charts Demo** (`/webgpu-charts`) - Visual GPU-rendered charts
//! - **WASM Example** (`/example`) - Rust-WebAssembly integration
//!
//! ## Performance Highlights
//!
//! - **Canvas2D**: 100K points in <3ms render time
//! - **WebGPU**: 816+ MB/s throughput, 1M points in 77ms
//! - **WASM**: <1ms function execution
//! - **Interactive**: Sub-millisecond hover detection
