Why PromptChart?
A safe, extensible architecture for natural language data visualization
🔌
Framework Agnostic
Works with React, Vue, Svelte, Angular, or vanilla JS. One component, any framework.
ðŸ§
LLM-Powered Intent
Natural language is converted to a validated JSON spec. No SQL generation, no code execution.
🔒
Safe by Design
Schema-validated queries with allow-listed fields only. The LLM never touches your database.
📊
Flexible Rendering
Supports Chart.js, ECharts, or Vega. Bring your own charting library.
🔧
Pluggable Adapters
Connect to SQL, REST APIs, CSV files, or custom data sources through a simple adapter interface.
