Image-Charts

API

Static chart, QR code, and graph image generation API

Overview

Image-Charts API enables developers to generate static chart images (line, bar, pie, etc.), QR codes, and graphs via RESTful endpoints. Customize outputs using URL query parameters (e.g., chart type, dimensions, colors, data points). Responses are high-quality PNG, JPEG, or SVG images—no client-side JavaScript required. Ideal for embedding visuals in emails (JS-disabled environments), PDFs, static reports, or dashboards where dynamic rendering isn’t feasible. Supports real-time data integration for up-to-date static visuals.

Example Integration (JavaScript)

script.js JS


fetch('https://documentation.image-charts.com/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
