AntV Infographic — AI-Powered Infographic Generation Framework

Introduction

AntV Infographic is a framework from the Ant Group visualization team that generates and renders rich infographics from structured data and natural language descriptions. It bridges the gap between raw data and publication-ready visual content by combining layout algorithms with AI-driven content generation.

What AntV Infographic Does

• Generates complete infographics from text descriptions or data inputs
• Provides a library of layout templates for different content types
• Renders responsive SVG and Canvas outputs for web and print
• Integrates with LLMs for automated copy and annotation generation
• Supports interactive and animated infographic outputs

Architecture Overview

The framework consists of three layers: a data-to-layout engine that maps input structure to spatial arrangements, a rendering engine built on AntV G (Canvas/SVG), and an AI content layer that uses LLMs to generate titles, annotations, and narrative text. Templates define the visual grammar while the AI fills in context-appropriate content.

Self-Hosting & Configuration

• Install as an npm package in any JavaScript/TypeScript project
• Configure LLM provider (OpenAI, local, or custom endpoint) for AI features
• Customize themes via JSON configuration files
• Static rendering mode available for server-side generation
• Export to PNG, SVG, or PDF for print workflows

Key Features

• 50+ built-in infographic templates covering timelines, comparisons, and flows

• Responsive layouts that adapt from mobile to large displays
• Animation support for web-based presentations
• Plugin architecture for custom chart types and layouts
