Gladly

A lightweight, GPU-accelerated plotting library with a declarative API.

Overview

Gladly combines WebGL rendering (via regl) with D3.js for interactive axes and zoom controls. It features a declarative API that lets you create high-performance plots with minimal boilerplate.

Key Features:

• 🚀 GPU-accelerated rendering using WebGL
• 💨 Zero JavaScript loops over data - all processing in GPU shaders
• 📊 Declarative plot configuration
• 🎯 Interactive multi-axis support (up to 4 axes)
• 🔍 Zoom and pan interactions
• 🧩 Extensible layer type registry
• 📏 Quantity and unit-aware axis management
• 🎨 Supports all standard colorscales
• 🔗 Subplot axis linking
• 🌈 Axis to coloring or filtering linking
• 🌎 Basemap layer with XYZ,WMS and WMTS support and CRS reprojection
