Image-Charts

Image-Charts generates static chart images on demand so that software teams do not have to build and host their own chart rendering service. Each chart is described in a URL, and the API returns an image that can be placed in an email, a PDF, a document, a chat message or an img tag. It supports bar, line, sparkline, pie, donut, radar, polar, bubble, scatter and GraphViz charts, Chart.js configurations, time series and QR codes, with retina output and localization. Developers use SDKs for JavaScript, Python, PHP, Java, Ruby and C#, while no-code users connect it through Zapier and Make. It was built as a replacement for the retired Google Image Charts service and also offers an on-premise version.
