DataViz

Acerca de

DataViz is a powerful Go library offering high-level charting APIs built on a flexible rendering stack. It provides implementations for common chart types like line, area, bar, scatter, heatmaps, pie/donut, and stat cards, supporting both high-quality SVG for web and an interactive terminal output for CLI tools. Beyond a standalone charting library, DataViz includes a Model Context Protocol (MCP) server, equipping AI agents like Claude Code with 29 specialized chart generation tools for seamless data visualization integration. Its layered architecture ensures versatility, allowing developers to utilize its underlying layout engine independently or leverage its full charting capabilities, all while remaining data-source agnostic and optionally integrating with design tokens for consistent styling.

Características Principales

• Dual output modes: High-quality SVG for web and terminal rendering with ANSI colors and Braille dots.
• Comprehensive charting API: Supports line, area, bar, scatter, heatmap, pie/donut charts, and stat cards.
• Model Context Protocol (MCP) server: Offers 29 chart generation tools for AI agent integration.
• Time-series and generic data support: Visualizes data with `time.Time` types and generic `interface{}`/`float64`.
• 1 GitHub stars
• Layered architecture: Separates layout, renderers, and high-level charting API for flexible use.

Casos de Uso
